Hello, noob here just wondering if there are owners or users of the 5.7 and what you all think in general.

I am humbled by the wealth of knowledge and collective experience this forum represents.

Thanks to all of you.

It's best suited to the Ps90 rifle.

The 5.7 pistol really deosn't do anything that a Glock 19/ 1911 deosn't do better.

The 5.7's primary purpose is CQB and less likelyhood of friendly fire/overpenetration after hitting your target. It's supposed to be a little bit on the weak side. My rifle seems to outperform my Glock 19, the pistol seemed a hair less powerful than my Glock 19.

It's a handy round to have for this niche use. But not too well rounded after that. I sold my 5.7, but my Ps90 is a keeper.
 
I like the pistol very much. It's been reliable, accurate, soft shooting and fun. The only drawback to owning one is that some indoor ranges ban it from use.

Ammo is plentiful. I see it for sale from $15 to $18 at gun shows.

It is an expensive gun. I bought at a gun show for $700, and can't honestly say I'd spend full retail price for one unless I had a compelling reason.
 
Nice, I didn't realize the Ps90 was 5.7 as well, my wife posed with one, and she was smiling,

does that mean I can get one?

Yes, they are pricey, and that's partly why I was undecided. :)

It doesn't do anything I need done, in any way in which I need it done.

It was designed to:
  1. Penetrate a steel helmet
  2. Penetrate body armor
I don't expect to need to do either of those things any time soon. Otherwise it's just a VERY expensive way of varmint shooting with a handgun. I'd rather use a S&W revolver converted to .22 Harvey Kaychuck.

When armed robbers and home invaders around here start wearing helmets and armor, I'll use my AR15 or Garand.

The USG model of the PS90 (black ringed sight) is being discontinued. CDNN has a close out on these at just over $1100 - if they have any left. Now's the time to grab one :)

I've fired one. Very minimal recoil. It might be interesting ... if the darn pistols weren't $1,000. Come on, FN. It's a freakin polymer gun, just like anything else out there. Why are the FNP and FNX reasonably priced, but not the 5.7?

One more comment is that I see it advertised as being good for women -- those "Ladies Home Companion" ads in gun magazines. I don't get this. That grip is FAT. Any woman with hands small enough to have issues with some pistols will definitely have an issue with the 5.7. The recoil would be a nice "chick" cartridge, but definitely not the gun it fits in.
 
My son talked me into buying one, and boy am I glad I did!

The pistol is great fun at the range. Very soft recoil, great ergonomics, wonderful SAO trigger, and a seriously cool muzzle flash. The gun is very light, simple to disassemble and clean, very functional and easy to see sights, with either 20 or 30 round magazines. What's not to love?

(Round leaves the pistol at about 2200 fps, which is why some ranges don't allow it.)
 
I've long thought that it would be cool to own one just for the fact that for a long time it was pretty much the highest capacity gun you could get in a standard sized gun. Gotta have plenty of rounds for the zombies :p.

The Kel-tec PMR-30 has now caught my eye on that front though. .22WMR is cheaper per shot, potent enough to have fun with, and the gun holds 30 rounds. You can also buy about 3 of them for the price of a Five Seven, IF you can find them :).

LOL Thanks Zero, added bonus would be more ammo to handload... sweeet!

My Lyman manual implies reloading the 5.7 isn't recommended due to the difficulty.

Sure it does. The original 5.7 round was armor piercing, but light and small enough not to overpenetrate. Civilians aren't allowed to have it, so we're left with standard lead core.

Personally I don't see the point of the Five-seven. Fired one a the range, didn't recoil any less than my 9mm. Cost twice as much.
 
Thanks for the dual wield Ps90's Ship, and thanks to all for your input~!

I was curious and perhaps I will just start another thread on "first handgun for a handloader" :)

PS - How about something for zombies w/ helmets and vests? :D
 
5.7

I have the FiveSeven pistol. All the positives mentioned above apply. Did I mention accurate?
Here's five consecutive shots with a 35 grain bullet, benched, at 100 yards. About four inches - gotta count the flier, don't we? Kind of a varmint pistol.

And this one - different load, a 55 grain FMJ. Shot lower and more open but again about four and 1/2 inches c-to-c.

How can a bullet be designed not to over-penetrate but go thru steel at the same time?

Sure it does. Penetration of thin hard barriers like helmets and dry ballistic weaves like kevlar is significantly different from penetration of wet soft tissue. The light little bullet and the highish speeds it runs at allow it to pass through thin hard barriers pretty well, especially using the original basically armor-piercing ammunition that isn't imported anymore, but it slows down FAST in soft tissue.
 
In truth the 5.7 is effective for personal defense, however in my CHL course in Texas the bullet size of 5.7 was to small to qualify with.(In other words not allowed to qualify with on the range section of the course.)
 
I had a 5.7 pistol. I found it a bit boring and ended up trading it away. I got a good deal when I bought it and ended up breaking about even. I appreciated it for what it was, and could be, but it failed to reach the level of a "keeper". That said, if I ever see another one at an extremely good price I might be tempted, but probably not.

On the other hand, my PS90 is most definitely a keeper.

Wow Pete, I'm thinking thats impressive! I'm reading the small caliber angle, etc. all great input, Thanks
 
A buddy of mine got one when they first came out. I've shot it several times. It's fun to shoot and looks really cool. It's also lefty friendly. The 5.7 ammo I've seen here in east tn is around $25 a box. Accuracy and reliability is on par with glocks in my experience.

High speed small caliber rounds snap right through hard objects. But they stop very quickly in soft objects. 5.7 penetrates alot more impressively in hard dry phone books compared to 9mm, than it deos in Jello.

Example:
Some thinner steel body armor can be penetrated by 5.56, but often stop more powerful .308s.

Polymer body armor can stop 5.56 easy, but .308 flys right through.

So layering polymer and steel is best, unless you don't mind carrying a thick steel plate. ( I think the good plates like these aren't civvy legal in communist America)

Just out of curiosity, what is the minimum they require? When I did my South Carolina class several people did the range qualifications with .22LR. I was TEMPTED to take my Ruger .22LR in there as I shoot better with it than any of my other handguns, but I'll admit, I just felt it didn't seem masculine enough to shoot a .22 there knowing I'd never actually carry it (and true to form, everyone I saw shooting a .22 there was female :)) and decided to qualify with my SIG P6 instead.
