FN FiveseveN Warning *Picture Heavy*

Do you have any suggestion as to what firearm has absolutely no chance of OOB firing.

I guess you missed my followup. I tested my EAA Witness and if the barrel and slide is not locked up it won't set of a primer. If the barrel is cammed into lock up it will set off a primer. IMHO any non-blowback pistol that don't have this behavior is defective in either design or execution.

"Absolutely no chance" doesn't exist for anything other than violation of the laws of nature -- things like heat flowing from a colder object to a hotter object etc.

If a locked breech gun fires out of battery, it is defective. Why the gun is out of battery is not relevant to the danger of a defective gun that fires out of battery. The defect can be by design, manufacture out of spec, or from abnormal wear. I try not to buy guns defective by design.

It seems the FiveseveN is a blowback design. High pressure round and blow back operation is IMHO asking for trouble!

I was thinking about getting a FiveseveN for its uniqueness, but I want no part of a high pressure blow back pistol for which setting off a primer 1/4" out of battery is considered "normal". Firing this much out of battery has excessive head space and grossly unsupported case failure modes -- a twofer I will run away from.

If a firearm fires OOB after a trigger pull something is unsafe for sure. Could be design defect some part defective whatever. But all OOB discharges do not begin with a trigger pull. A problem with ammo or broken gun part. It may happen before the operator has a chance to pull the trigger on the fine firearm with the wonderful OOB design.
Because of the design of this firearm it may well shake out in the future that reloading is not good for the FN ammo or firearm.
I think this firearm design/ammo combo is capable of case head seperation that does not involve OOB. :what::eek:

I would get a good lawyer. Most will probably pick up the case for nothing based on the potential return of the lawsuit. The reloaded bullets that are left can be examined by a third party to make sure they are (and I'm not doubting your reloading skills) within specified ranges. Once this is established, reload or not, the weapon can then be the focus of the litigation to prove that it is a potential danger to consumers. excellent pictures by the way. Lots of luck

Yes, but this won't tell what happened to the round that failed. Reloading problems rarely happen with every round unless the press is simply set wrong. Instead, problems tend to be rarer. That is the sinister aspect of reloading-not achieving absolute consistency.

Yes. I experienced a problem with some Mag Tech ammo not seating properly in the chamber of my HK USP Elite. It held the slide out of battery by just a whisker, but yet the pistol would not fire. I thought the trigger had broken. It was a real WTH moment and it took me a while to see the problem... it was so slight.

A Kahr P45 did the same thing except it was held out of battery by a larger, more noticable margin.
 
Most of the centerfire pistol cartridges out there above 9MM have a higher pressure than the 5.7 what plastic pistol would you be shooting then?

Actually, the reverse is true. Only a handful of handgun rounds operate the 5.7's 45,000 PSI. And they don't come in polymer guns.

Yes, most well designed firearms include some sort of a disconnect for a slide not going all the way in battery. This is not the only way to have a OOB discharge. Defective ammo, a part breaking including the dissconnect, foreign matter in the firearm, can and have caused a round to fire OOB. No firearm is immune from this not even your H&K or Witness. Every case of OOB firing is not preceded by the trigger being pulled.

Actually, the reverse is true. Only a handful of handgun rounds operate the 5.7's 45,000 PSI. And they don't come in polymer guns.

Yes, this is true and have you noticed those rounds that do operate higher are chambered in heavy frame revolvers.
The 5.7 fires every round with an OOB or ecessive head space type condition if you want to look at it that close. If you read the patent and think about the operating system the slide and barrel are seperating while pressures are still high enough to stretch the brass .050" between the case head and the shoulder. At these pressure levels it would not take much extra to seperate the case head. No OOB condition need exist. :)
 
I'll just steer clear of these high pressure whizbang plastic fantastics.... not that my 1911 is idiot proof, but it sure is more forgiving.
 
also note that the cases were once fired some maybe twice fired.

with bottleneck cases, keeping track of how many times the case has been fired is mandatory, because of the stretching issue.
 
Clearly looks like a reload problem to me.

I'm not in the market for a 5-7, but this incident certainly wouldn't deter me from buying one.

I would be sure to fire only new name brand factory ammo, though. Forget about reloads etc.
 
f3rr37,

FN asking for the pistol back isn't out of the ordinary. They want to examine the failure mode. You are clearly out of the warantee on this one. I speak from experience. My GLOCK 22 had a moment when it decided it didn't like being assembled anymore and it's various parts went in many directions. I was using reloads--nothing experimental and very carefully assembled. Doesn't matter. I checked with several Lawyers, all concurred, I had no recourse. GLOCK made me the same offer FN has made you. They sent a call tag, I shipped the pieces of the pistol back, they destroyed it, and sold me a new G22 for $250 IIRC.

Destroying the old pistol isn't destroying the evidence, it is making it possible for them to send you a new pistol (directly) in place of the one you no longer have. I believe you can look this up on the BATF website. It is important that you get a quote on what this new pistol will cost you so you understand what the total cost to you will be. In my case, the G22 was sold unfired to buy my USP compact.

The issue of medical bills and hurt feelings won't be addressed by the company and no attorney is going to be able to make the company "make it right". Cut your losses and decide if you want the new gun on their terms. If you decide to get it, decide if you are committed to the platform or sell it and get something else.

I'm glad your hand is healing.
 
I am posting this here as being informational.

Second Item:

The Five-seveN will not fire out of battery as claimed and falsley demonstrated on this post.

The Five-seveN slide will move rearward .1540-.1545" before it is considered out of battery. This measurement can be taken by pushing back directly on the barrel. After that point the barrel lug is locked and the slide will continue to move rearward. Now you are considered out of battery.

Up to this point the hammer can still fall but you will not strike the primer. The hammer will strike the bottom of the slide and not the firing pin. At .0840" of slide travel the firing pin disconnect is out of reach of the firing pin safety. The firing pin safety is the part that lifts the firing pin block out of the way allowing the firing pin to travel forward after being struck by the hammer.

Third Item:

Do not reload this cartridge unless you completely understand this system!

If you do not create the appropriate pressure at the appropriate time you will create a catastrophic failure. I am not saying this is what happen in this case, so let me explain.

The 5.7x28mm has been through milions of dollars of testing to make sure this does not happen. I am sure that no one on this forum or any other has put in the time to develop the exact timing needed to produce the proper timing of this cartridge. Without this timing and proper development of pressure at the exact time you can cause the slide to start the rearward progression too early. This premature movement will result in the pressure spike occuring after the case has been partially removed from the chamber. And I beleive everyone knows what the end result is.

Pressure from the expanding gasses will folloow the path of least resistance. If the case is partially removed before it has developed all the pressure quess where that path is now?

The cartridge is designed to form to the chamber during this process, this is why it the shoulder is not the same after firing factory ammo. The shoulder forms to the chamber and is all a part of this critical timing.

I personally would not reload this ammo. I am saying that as one man to another, not because of company policy. I reload, I have loaded more than 500,000 rounds of .38 super for competitive IPSC/USPSA competition. I understand the need for reloading as it does save money and you can create a load that works for your needs. This cartridge is not as easy to load because of the timing and pressures. It was never intended to use heavy bullets with high velocities. Light bullets create the high velocity not heavy bullets.

I will post more on Thursday...

The only reason FNH USA would keep someones gun that is sent in for repair is due to BATFE regulations.

If a firearm has to be replaced then it must be destoyed per BATFE regulations. A manufacturer cannot issue a replacement of a serialized item without properly destroying the first serialized item. This is public knowledge and if you are not aware of this take it up with BATFE not FNH USA!

Couldn't let that one go over night...

You know it will be a good story when there are dates, times, and the word "reload" and the word "test" in the opening statements. It usually means the testing wasn't successful.
+1

I reload, too. I know that if I blow up a gun, it is almost assuredly my own darn fault. I looked at the load data on the Ramshot web site here: http://www.ramshot.com/powders/

Their guide has load data for 35, 40, and 45 grain bullets for the 5.7 cartridge. They do not show any load data for 55gr. In addition, they have the following special note for the 5.7 caliber:

1) This is an extremely sensitive caliber. Please adhere closely to indicated loads and COL guidelines.

2) Always begin loading at the MINUMUM start load and increase only in increments of 0.1 grains.

So let me see if I have this straight. You are reloading in an "extremely sensitive" caliber, using a bullet/powder cartridge combination for which there is no load data, in a blow-back pistol, and you are A) surprised that you got bit and B) believe it is FN's fault? And your response has been to flood the internet, on multiple forums, with your tale of woe, blaming FN and doing your utmost to besmirch their corporate name.

If I was FN, at this point I'd simply say A) owner's manual says don't use reloads, B) you said you were using reloads, therefore C) go pound sand. No, I'm not an employee of FN nor do I own any FN products.

Your injuries were (and probably still are) undoubtedly painful, but it appears that you will fully recover. Be thankful for small favors and move on with a lesson learned.
 
I've spoke with Bob Alies the customer support manager at FN before, his knowledge and customer service stinks!! My initial gripe with Bob was that I could never get a hold of him, every time I call it went into Bob's voice mail and I mean EVERY TIME!!! I've tried emailing Bob about some concerns ive had and never receive a reply. When I finally did get a hold of Bob, he told me his boss was out of country at the moment but when he got back he would get an answer to my question. I have yet to hear back from anyone from FN.

This is my email to Bob, its a simple question dont you think?

04-08-2008
Hey Bob, I just got off the phone with you. Here is the question and the pictures.

My question is... Looking at the FNH SLP 18" version I've seen two different setups, I've noticed that some SLP 18" versions have longer barrels then others. Do the older SLP's have true 18" barrels while the newer SLP's have 18.5" barrels? I'd like to know when they started doing this and why? Any info on this would be great! THANKS!!

It would be interesting to see what Ruger or Sig Sauer would come up with if they designed a pistol that used this cartridge.

I would think that the very nature of this cartridge, being as high pressure as it is, would demand a pistol design that is not only rugged, but that also was designed to offer some protection to the user in case of a Kaboom type failure. This ain't your father's 1911, after all.

Creating a polymer handgun that can fire a high pressure round out of battery, even by just a little, just doesn't seem well thought out to me.

To my mind, the FN Five-seveN lives right on the hairy edge of acceptability.
 
The 5.7 is a gun that was designed very specifically around a cartridge. The general rule of thumb is if you have a weapon that is designed around a cartridge, you don't experiment with that cartridge, because the weapon is already designed to maximum performance, and pushing the envelope is asking for trouble, as it is well demonstrated here.

If you want to have fun reloading, reload a .45, or other straight wall cartridge. Any kind of gun that was built, and then a proper cartridge was suited to the gun.
 
To Whom This May Concern,


I am writing this letter in request of Tommy Thacker per our conversation on this date at 7:38PM Pacific Standard Time, requesting “nothing but the facts” of the incident that happened on April 12, 2008, while I was out target shooting my FNH FiveseveN IOM pistol.


On Saturday, April 12, 2008, at 1528HRS I was out target shooting and testing some ammunition that I had reloaded.

I had loaded 200 rounds of the following:
Bullet: Hornady 55grain FMJ BT
Case: Once (a couple might have been twice) fired 5.7x28mm brass
Primer: Winchester Small Rifle
Powder: Ramshot TrueBlue 5.0grains
Case Length: 1.128in + or - .002in
OAL: 1.580in + or - .003in

I load every single round by hand using a Lee hand press, RCBS 5-0-5 Scale, RCBS calipers, RCBS seating die, etc... Each round is placed in front of me with plenty of lighting while I am measuring powder, then after all powder is measured and placed in the cases I inspect the case for powder, as even 1.0grains more or less is quite easy to see, then placed in the hand press, topped off with a bullet, and then the bullet is seated. If the powder was double charged it would fill up into the base of the case's neck. Like I said, cases are inspected for overcharges.

Back to the accident. I had fired 66 rounds all reloads of various bullets (Hornady 40grain VMAX, pulled 28grain HP from SS195LF, Hornady 55grain FMJ). My 2nd 20round magazine I fired 5 rounds of 40VMAX I had some failure-to-eject (these were loaded with HS-6, I've had problems with that powder causing FTE), then tossed the magazine so I could pull those bullets and reload them with Ramshot TrueBlue. After that I fired 20 rounds off the 28grain bullets, all of which functioned flawlessly with Ramshot TrueBlue powder. The next magazine of 20 rounds was the 55grain FMJ with the load data above. The first magazine fired flawlessly, I even noted in my reloading book that it I might want to try loading to 5.1grains and see how they functioned. The 2nd magazine is when I ran into the malfunction, the first round fired like the previous 20, the it happened.

On the 2nd round I realigned my sights, slowly pulled the trigger and the gun literally exploded in my hands. I saw bits and pieces of the top of the slide cover blow. My first reaction was, "Oh crap what just happened." My second reaction was, how are my hands, I released my grip with my left hand (off-hand) and blood was trailing down my palm dripping off my hand. I could see 2 sources of the blood flow, one on my thumb and the other the web of my hand. I tossed down my FiveseveN into the grass in front of me and inspected my right hand. My right hand faired much better than my left, a small spot on the tip of my thumb.

I immediately pulled my cellphone out of my pocket and called my wife who had just arrived at my father's residence where I was at, I was ~1/2mi from the house. I told her to tell my dad to get out here, my gun just exploded, he quickly arrived and assessed my injuries. We went back to the house, cleaned my hand up a bit, bandaged it up, and went to the hospital ~40minutes away with my wife and mother-in-law.

Spent about 2 hours at the hospital getting 1 stitch in the web of my hand and 2 xrays. The xrays revealed a chunk of brass in the middle of my hand between my index and middle finger, and two very small peices between my index finger knuckle and the web of my hand. I have gone to a surgeon to see about getting the large piece of brass removed from my hand but he cautioned against it as it would cause more damage taking it out than leaving it in, as it is embedded into the muscle in my hand a probably isn't going to go anywhere so there isn't any worry about it moving around and slicing tendons and such.

I initially lost feeling in over 50% of my index finger and my thumb felt like it had been hit by a hammer and had numbness for about a week. I have gained some feeling back in my finger and am at ~35% complete numbness now.

My FN FiveseveN IOM is a complete loss, the magazine is still inside the grip, the remaining 18 rounds were forced out of the bottom of the magazine.


After looking over my FiveseveN I came to the conclusion that it had fired out-of-battery. There is 0 damage to the chamber and barrel that I can see. From what I can figure the round fired (out-of-battery) and the case was able to hold the pressure enough to allow the bullet to clear the barrel and the case wall gave way in the rear because it wasn't being supported by the chamber. The expanding case broke off at the neck while being extracted and as you can see from the photos above the whole back end of the case gave way. One chunk of brass is embedded into the right side of the grip, I almost had a matching chunk of brass in my right hand, but the grip stopped it.

After talking with a few friends and showing them my new paper weight they came to the same conclusion. Ryan from Elite Ammunition (www.eliteammunition.com, Custom 5.7x28mm Ammunition, both reloaded and virgin brass loads) also concluded that the cause was from it firing out-of-battery. He also stated that he has observed that with the FiveseveN the hammer will drop at up to 1/4inch out-of-battery.
I contacted Robert Ailes the Customer Support Manager at FN, 703-288-3500 ext 122, [email protected], on the 14th of April and told him my situation. He told me that he would talk to his boss about it and contact me the next day. Also told me that since I was shooting reloads that the warranty on my gun is void.

Next day, no phone call, so I called after hours and left a message for him to please return my call and gave him my cellphone number. So around noon on the 16th he called me and told me that "someone" would be contacting me soon. I asked when they might be contacting me and he said he did not know, but they would be in touch. I also asked how much it would be to just get it fixed/replaced and he said he didn't know, I would have to talk to the person who will contact me. I was expecting a call from FN's legal team...

April 28th... I called and left a message for him, asking him what the situatino was and when/if someone was going to contact me. At this point I pretty much felt as if they were just waiting for me to go away so they wouldn't have to deal with the situation.

April 29th... Rober Ailes returned my call and said the best they could do for me was send me a pre-paid packing slip that would be here by Thursday (May 1st) to ship the gun to them so it could be looked at, held for 30 days, then destroyed. I asked if I could get it back after they looked at it, and he said no and that it would be destoryed. He also offered me a "deep discount" on a new gun, but gave no details as to how much it would be.


I've been in contact with Tommy Thacker over the past few days via fivesevenforum.net, voicemail, and our conversation tonight. I never once wanted to blame FN for my problem, however after reviewing my original post, what I posted and what I really meant didn't not come out to be the same, for that I apologize profusely for. When I talked to Tommy I told him 2 or 3 times what my intent was with my post and he told me that that is what he got from my post. My post was out of frustration in the abundance of broken promises that I had received. I wanted to see if someone else could get more information than I could from FNH, because from the half dozen telephone calls that were made and received I had been told numerous things and they never happened. I never asked for anything from FNH, I just wanted to know if someone would want to take a look at what happen to help me understand further what caused this problem.


I will post this response to FNH on fivesevenforum and other places I posted. I will also do my best to contact any other places that my incident has been posted to.


I thank you for your time and sorry for any inconveniences that I have caused Robert Ailes, Tommy Thacker, and anyone else at FNH. I tried making clear in my post that all I posted was my observation and nothing more. It seems that this was blown out of proportion and beyond the control of the forum, myself, and FNH.

========
End of Letter
========

I talked with Tommy tonight, he said FNH wanted to take care of the problem, send me a new gun w/no questions asked. All they asked is that I send them a letter of nothing but the "facts" and they will send me a pre-paid slip to return the gun and they will inspect it and replace by gun for me at no cost.

I want to publicly thank everyone here, and everyone at FNH for their time and effort that was put into this. A lot has happened in the past few days and this has blown way out of proportion.

If anyone got from my original post that I was putting the blame on FN, my intentions were not such. Tommy even acknowledged that he did not feel that from my original post.

They are investigating and doing their own testing to see if an OOB fire is possible given all the variables of the situation.

I will try and update everyone as things happen.

Again, thank you all,
-Jake
 
On Saturday, April 12, 2008, at 1528HRS I was out target shooting and testing some ammunition that I had reloaded.

I had loaded 200 rounds of the following:
Bullet: Hornady 55grain FMJ BT
Case: Once (a couple might have been twice) fired 5.7x28mm brass
Primer: Winchester Small Rifle
Powder: Ramshot TrueBlue 5.0grains
Case Length: 1.128in + or - .002in
OAL: 1.580in + or - .003in

If you're not sure how many times you loaded an extremely high pressure (for a handgun) case, perhaps you shouldn't be reloading this caliber?

Jake, you really might not want to experiment with reloads again - at least, without making sure the pressure curve matches what the entire platform was designed around....

I take back what I said about OOB firing - at .130" (my measured slide-frame gap at the most when the hammer will fall) as it seems that the barrel and slide are still firmly together, as Mr.Thacker explained.
 
So FN says its not a blow back design, the barrel/slide are locked for the first 0.15" of movement.

What about the you tube video showing it firing a primed empty case at a claimed 0.25" out of battery? Did the guy measure wrong?

--wally.
 
See the lawyer...

Just because FN states in their warranty that they won't fix the gun if you're firing reloads doesn't mean they are off the hook in any sense of the word. Clearly something bad happened, and as somebody who spent a lot of years in mechanical design as an occupation, the "kaboom" didn't happen where it was supposed to.

Total up all your medical bills, the cost of the firearm, and get the phone records of your calls and letters to FN. Take them to your lawyer and let him tell you whether or not you have a case.

If I was sitting on a jury and the customer service manager said "after the gunsmiths examined the evidence we destroyed it", he'd be going to jail as well as paying for the company's liability. Whatever you do... hold on to the evidence, which is the gun and the reloaded shells you took with you, and get statements from your doctor regarding how you had to be treated for the injuries incurred.

I can post signs in a store that state "we are not liable if you are wearing flip-flops on these tile floors"... but if somebody slips and falls on a wet spot, see who pays. Just stating that you aren't liable for something doesn't absolve you of the legal responsibilities for design, layout, errors in production, faulty parts... any number of things could have contributed to your mishap, and FN simply stating that they won't replace your gun because you were firing reloads doesn't give them squat for legal protection.

The famous lady at McDonald's, who got a million bucks because she didn't realize her coffee would be hot when she bought it :what: is a prize example of product liability. An idiot would know that coffee is hot when it's right out of the brewer, but apparently the 12 people on that jury didn't think that McDonald's had done enough to protect this dummy from herself... so they punished the company.

Don't let the firearms company tell you what they're liable for and what they're not. Talk to a lawyer and then present it in court. FN may learn that customer service is the way to fix problems like this... not by trying to save money dodging the people who fire their guns with reloads.

I just sent a gun back to Smith & Wesson and they replaced the frame at no cost. They sent me a mailer, paid the freight both ways, and completely rebuilt my pistol. It took one phone call and $2 for the mailing box. That's customer service...

Also, you might be able to file a claim against the insurance at either the range where this happened or with the property owner's insurance where it happened. I can promise you if the insurance company has to pay out anything, FN will be in court with them recovering their costs... but whatever you do, don't let FN tell you they're not liable... put it in the hands of a professional and get a judgement from the court that they aren't liable.
