My Brand new Glock 19 jammed 3 times in 150 rounds.

[High Planes Drifter]

Ammunition was Monarch. Im sure its not the greatest ammo in the world, but it was brass case fmj, new manufacture. The first jam was a stovepipe while feeding. It was on the second round of a full mag. Where I messed up was not making a mental note of what mag it was. The second jam, the fired/empty case got caught in the ejection port. The magazine had maybe two or three rounds left in it. I made a note of which mag was in the gun this time. The third jam was the same as the second, and using the same mag. There were three rounds left in the mag.


Does this sound like a mag issue? Should I send the gun back to Glock, or go to the range once more without that imparticular mag and see if the gun works fine? This is the first time I've fired the gun, I was planing on making it my carry gun. Im pretty darned dissapointed.

don't worry i have had hadguns that have performed much much worse. i would say try different ammo first, then different mags, and if thr problrem stayes then send it back but i bet it is an ammo issue. maybe a mag issue but highly doubtful it is the gun.

 

[conan]

A 10 rounder used to cause jams in my 19, but when I went to a 15 rounder it became uterly reliable. Try a different magazine for sure.

Try ammunition made in the U.S.A. before blaming the gun or the magazines.

Any chance you were "limp-wristing" it? Some guns are more prone to this than others and require a firm grip to function properly. Even if a firmer grip does make a difference, I am not sure how much I would trust it in a selfe-defence situation untill I have it operating %100. Borrow another magazine, try different ammo and firm up your grip and see if any of that improver the performance. If not, It's time to contact the Dealer/Manufacturer.

I have seen some extremely nasty Monarch (.45 ACP though) before. Stuff was gritty and greasy for some reason. It jammed my friend's 1911 about every 5 or 6 rounds. I would recommend trying a different brand of ammo, and then if the problem continues contact Glock. New mags might fix it, but the gun ought to be 100% out of the box IMO.

limp wristing is another possible cause that i left out of my post as i figured that the op was experienced enough to not do, but with that said that is a good point and could be the cause, so check form, change ammo, then mags, then worry about returning the weapon.

though i think the ammo is the cause i have never had any issues with any glock firing any factory ammo. foreign made or not.

Limp wristing a polymer framed gun especially in 9MM is very common. You have to support the frame of the gun very well in order for the slide to reciprocate fully to the rear, the polymer framed gun flexes under recoil. Limp wristing can cause:
Failure to feed (not enough energy from the slide to strip the round from a loaded magazine, especially in some of the really high tension double stack magazines, ie.. Glocks).
Failure to eject (stove pipe) because the gun is not supported well enough for th slide to move far enough or fast enough to eject the empty cartridge.

Weak ammo can contribute to this also, combined with weak wrist equals bad results.

The green-box Monarch 9mm is brass/boxer Prvi Partizan which is loaded a bit hotter than run of the mill Winchester White Box. It runs clean and warm... so I'm not sure I'd blame the ammo in a NIB weapon.

Maybe Glock has realized that the high-end 1911 manufacturers can get by with saving money on final fitting and finishing by requiring a 500 round break-in and began doing the same thing?

 

[Beowolf1911]

As much as I would like to say it is because you got a Glock, fact is most pistols need a 300-500 round break in period before they work as good as they should. I would take it out a few more times try the different mags and see if it was a mag issue and strip it and clean it thoroughly before I would go to the manufacturer. You might want to try a heavier load, since the recoil spring might still be a bit tight.

 

[strat81]

First, try a tighter grip. Then try better ammo.

My father-in-law gets my G26 to jam constantly because of his grip.

 

[weisse52]

It seems you may have noticed it more with one magazine. This could very well be a mag problem. I agree with your thought to leave it out of the mix next time you shoot. I number my mags to keep track on number of rounds and performance. While I have had excellent results with my G19 it is something that can happen.
Give it a chance with some different ammo next time as well.

 

[DENALI]

Your Glock you said is NIB and assuming this is correct check your mag followers, are they rounded or pointed? Glock has been messing with there mags and the point'y ones I've found to almost always require some breaking in. I noticed this the past two years or so and am almost positive it's not the pistol itself. I had the same problem with a 22 and took the mags apart put em back together and never had the problem again. It's very rare to encounter this type of thing and have it end up something other than the shooter or the mag, check the mags! Good luck

Give it at least 400-500 rounds of break-in time before you chalk it up as a lemon. I just picked up a "LNIB" 19 that had 75 rounds through it, and the action is still extremely tight (not rough, but very stiff). Dangfangled Glocks last so long, it takes near half a case of ammo just to get 'em running

 

[10-Ring]

I woul give the gun a good clean & lube, make sure to take a more secure grip and maybe try a different mag or two...
good luck! You rarely hear of reliability issues w/ 19's, hope this is just a fluke!

 

[High Planes Drifter]

No way was I limp wristing it. I am an experienced shooter. My .45 collection consists of 2 1911's and a Sig 220. I never have jams with them. The Glock doesnt recoil anywhere close to my .45's.

Try ammunition made in the U.S.A. before blaming the gun or the magazines.

Is there a common known problem with Monarch 9mm?

 

[distra]

Glock...jam...impossible! At least according to the Glock owners I know. It's always the ammo's fault. My guess is you need to strip it down, clean it a bit and lightly lube the pistol. Give it a couple hundred rounds and if you think ammo is to blame run some WWB (Winchester White Box) through it. If you still have issues after 500 rds, send it back for repairs.

No

 

[pbearperry]

Glock problems

I would go back to the range with a different mag and ammo and see if the jams occur again.My old Department has had Glocks and never any jam problems.

 

[PoconoEagle]

sorry I cant help much except say my sig's never did that

 

[cdcmj]

you should have just gotten an XD 9

 

[Mad Magyar]

but i bet it is an ammo issue.

In a FMJ, not hardly in a n.i.b.....How much ammo will you fire/waste to determine the break-in?
If it was me, I would give it a good cleaning and using the mags provided by Glock: try it again in FMJ..If it fails, ask for a refund; not the repair nonsense and purchase something else....

Because your 1911's work and your Sig 220 works doesn't mean the Glock will work if your grip is anything less than perfect, especially with the G19/17. You will be hard pressed to limp wrist a 1911 regardless of your grip (same is true of the P220).

First, I would strip the pistol and look at the slide rails and frame rails. Look for plastic cast over the rails (rails should be showing all steel) or look for signs of excess friction (worn finish in the slide rails, metal shavings, etc.). If it looks ok, then it's probably not your gun.

Stove pipes in the G19/17 models typically come from limp wristing, weak ammo or a combination of both. The slide velocity is minimal under such conditions and the gun fails to function as intended.

Does the slide lock back to the rear on the last shot reliably?

Anyway, here's what happens when a Glock isn't properly held.



Here's a different Glock (17C) doing the same thing.



Here's a test showing that 1911's don't suffer from this problem.

It's a Glock, not a Kimber. There is absolutely no need to break in a Glock.

 

[weisse52]

I think the best advice given has been clean it, different ammo, different Mags.

If that still fails then give a call to Glock. I agee that I have had four Glocks and never had to break one in, nor have I ever had this problem. NOTHING is 100% foolproof and sometimes a problem can occur with ANYTHING. Glock stands behind the product.

So give it another try and let us know how it went.
