Glock perfection?

Just thought I would throw this out there so its documented. My glock 22 jammed twice last Friday. I was shooting some fiocchi through it and it jammed, then again 5 mags later. I had one box of fiocchi and three boxes of blazer. The blazer gave me no trouble. I bought the gun in October and haven't fired it since, but its never jammed before. And yeah, the gun is well maintained.

I'm not worried at all. I talked to one of the range officers and he said fiocchi seems to do that to a lot of guns. He thinks its because they "run hot" meaning they pack more powder than other brands. As well as the shell casing seems to be a bit thinner.

I'm just putting this out there because I hear a lot about how glocks never jam. Never thought I would see the day, but my opinion doesn't mean much (still a noob).


Anyway, lesson learned. Don't cheap out on the ammo!
 
i've only had 2 double feeds and 3 or 4 stove pipes, the stove pipes are when i'm running soft load. and the double feeds happend durring a ipsc match and i did'nt stop to see if i could see why - drop,load and go

I've put 1000's of rounds since my last double feed
 
A Glock is a mechanical devise and all mechanical devises can and will fail.
I've changed several broken extractors and trigger springs on several different Glocks.
Good pistol all the same.
 
My G26 would jam occasionally with a one handed or limp wristed or around barricade sloppy/loose grip. Using HOT Can Issue IVI 9mm ball helped. The G26 has a VERY short triple wound spring, and prefers HOT ammo.

My .357 SIG conversion barrel in my G 22 goes click a LOT ....
but I bought a case of OLD ammo .... 1000 Remington 125 gr factory .357 SIG ammo .... at the price of the brass, and the seller threw in 500 primers. Some boxes of 50, I'll get one FT bang, other boxes, I get SEVERAL, so I get lots of practice at IAs and stoppages.

My G22 failed to go BANG with .40 AMMO only once. I am constantly swapping barrels between 9 mm, .357 Sig, and .40, and one time something just wasn't right ... even though the mag full of .40 had about 5 rounds go bang, THE OTHER 5 rounds DID NOT.

On checking the primer hits, they were all good solid deep impacts,
BUT ALL 10 RDS HAD THE FIRING PIN HIT GROSSLY OFF CENTER ... WAY HIGH.

I can only assume that some crap got between my barrel and slide [ ? brass shaving? ], and while the barrel and slide would go into battery, and the firing pin would go forward, the barrel didn't get all the way up properly into lock up.

I say assume because when I stripped the slide, I didn't find nuthin extra in there ... and I never had that problem again.

PS: Check your Fiochi fired brass for massive bulging at the rear, where the stock GLOCK unsupported chamber is pretty sloppy. If you see big bulges, there, then that ammo is too hot for that chamber ....
maybe look into a tighter chambered aftermarket barrel.

good luck with this one,

Doesn't sound like the range officer knows what he's talking about. Usually, it's the underpowered ammo that causes jams because the slide does not have sufficient velocity to complete the cycle.

Personally, I've never had a problem with Fiocchi 9mm or .45ACP ammo, though I haven't tried their .40 cal stuff.

It's true...I just want guns that will be 100% 98% of the time, and then for about 66% of the remaining 2% I find I can do a tap rack, and that will clear 95% of jams, and 5% will need further action. 34% of the time I go immediately to either pulling the magazine and racking the slide with about 300% force, and replacing 100% of the rounds, or, maybe 2% of the time, I apply about another 15% effort to driving the slide the last 5% into battery.

This simple formula has a success rate of about 99%, 100% of the time I am shooting my Glock, which is about 70% of the shooting I do these days now that I am 40% busier at work.

He was saying that because the round had more powder, the slide would go back and come forward faster than usual causing the next round to stove pipe.

I think hes got a good handle on things lol.

This is not a stovepipe. A stovepipe is when an empty rounds fails to eject and gets caught up in the ejection port pointing upward (hence the term "stove pipe"). What you're describing is known as a misfeed (live round failing to go into battery).

I still don't see how a misfeed could be caused by the slide traveling too fast unless the extractor somehow managed to skip over the case rim? Did it?
 
I've fed my 17 + 21 everything from ivi and +p to low powered production stuff.
I think the majority of issues come from user error and not ammo as some would profess
 
Any new gun may jam due to various reasons it just needs to be broken in, some ammo may give you trouble too, or a particular magazine.

I thought of that too. I think I might not be gripping the pistol strong enough, allowing it to kick back more than it should. Something for me to keep in mind. Thanks.

I have found in having trained a great number of people on the Glock that fails to feed are almost certainly user induced.

The Glock 22 I've been shooting for several years that has > 30,000 rounds through it has never had one fail to feed, fire, extract or eject.

NAA.
 
What type of jam did you have? Was in a Fail to feed or a fail to eject? Or did the round not chamber properly? Stove Pipe?

I have had problems with my duty pistol and a crappy lot of ammo we had. Twice in one day I had a misformed casing that didn't fit all the way into the barrel. If went in half way and just jammed in there. It was all the srtength I had to pull the slide back to get it cleared.

If you're having fail to feed issues, your more than likely going to look at the mag spring to see if it have lost a bit of tension. If your one of those guy that leaves a fully loaded mag in the night stand, that could be your problem. The springs just wear out and they need to be replaced.

Stove pipes are more often then not caused by damaged feed lips on the mag. Check and see if they are bent a little. This would allow the round to stand on end when it is cycling out of the mag.
