Glock problem

Hi, I have a problem with my Glock 17. I purchased it a few months ago, and it seems like every tenth or twentieth round the gun will jam. I use only new ammunition, and I keep the gun as clean as I can. What could be the problem here? Thank you for any advice.
 
What kind of jam??? Is it always the last round in the mag??? (assuming you have Klinton mags) Does it happen with all of your mags, or just one??? Get the feeling that I think it's a magazine problem!!!!????? When did it start happening??? Have you CLEANED your magazines????????? ;) Data, we need more DATA!!!!!!!
 
?

What has always been happening?

is the spent case not being fully ejected?

is the spent case staying in the chamber?

is the fresh cartridge nosediving on the feed ramp?

is the fresh cartridge getting hung up on the way into the chamber?

is the slide locking back prematurely?

there are many people here willing to help but you need to describe exactly what is happening when you say "jam"
 
The cartridge is getting caught in the way to the chamber. I'll have to take out the round and afterwards if I try to fire it it usually won't work.

Sorry about my lack of detail.......I've gotta be a little more careful there.
 
What won't work? The round won't fire after the primer has been struck/restruck or it won't fire because the striker has not been cocked? What brand of ammo, grain, JHP or FMJ are you using and has it happened with a different lot #? Does it only happen when you shoot it one handed or with both hands?
 
I'm not sure exactly what it is about the round thats not working. Basically I pull the trigger and instead of firing I look at the gun and the round is jammed and the slide is stuck backwards, and I have to pull the slide back and get the round out. I've used several different brands of ammunition, such as Winchester and Center(or something like that). I only shoot two handed.
 
You maybe "limp wristing". Get somebody who does not typically have jams with a Glock to shoot it.

Still failing...need more info on the failure (double feed, FTE, FTF,...). Ideas:

1) empty ejects but FTF (failure to feed). Check and clean the mags. Look for burrs on the feedlips and front. Depending on where the hang up happens look at the barrel ramp. Burrs, dirt...

2) empty case does not eject (FTE). Check and clean the extractor.

3) what brand are your mags
 
Be sure ...


... you're not limp-wristing the gun. Check your technique.

Strange as it may seem, this can happen even with 9mm pistols, not just the heavier recoilers. And I've even seen it happen with subsonic 9mm "range ammo," which had the recoil-impulse of a mouse fart.
 
Why would me holding the gun too softly make it jam? I mean, one round will fire and the next one just won't shoot.

I have three factory mags and one USA mag, and they all perform about the same as far as I can tell.
 
Stop blaming the shooter

I'm really tired of all this talk of "limp wristing," especially concerning Glocks. Wow, if Glocks fail when held a certain way, and this happens less often with other pistols, wouldn't that make them better than Glocks? Where is this fantastic reliability Glock enthusiasts keep referring to?

Please, stop blaming the shooter. Maybe we shooters deserve a pistol that doesn't need a death grip to function properly!

Gosh, maybe the problem is with the Glock!
 
Did you buy the pistol new? Is it completely stock? No new springs or add on dohickeys?

and the slide is stuck backwards, and I have to pull the slide back and get the round out.

so you are saying that the gun is not going completely into battery? i.e. the slide is not completely forward? could be a weak recoil spring (but then you should be able to push the slide into battery and continue) or the reverse and the recoil spring is way too strong and severely denting the cartridge's case, possibly a tight chamber but I have never heard of a Glock with a tight chamber
 
"Why would me holding the gun too softly make it jam?" This is because you are taking up the recoil in your wrist-flex/arm-bend action. Essentially diminshing the amount of energy available to the weapon to cycle. It's simple to correct with your hold. Make sure your strong arm has a firm elbow and wrist. Death grip not required.

dcmorris: The advice given here is attempting to help a shooter new to a weapon not defend a manufacturer. The type of error being described is shooter induced and shooter corrected (barring obvious mechanical/ammo problems). It's analogus to "short stroking" a pump shotgun which is also an operator oops.
 
The gun is completely new, not used at all. I'm not sure if it's me or not, it has jammed when my father has shot it before and he has a marksman ship badge for pistols from teh Air Force, so I don't think he's 'limp-wristing' it. Someone once suggested that I need to have it 'throated', which apparently would involce scraping a little bit of the gun out. Anyone ever heard of that?
 
My G34 would do that with the 10rd Klinton mags that came with it. The round would hang up on the feed ramp. The follower on a Klinton mag is really funny looking, I figured it wasn't holding the ogive in the right relation to the feedramp causing it to jam.

I dumped them and got some real standard cap mags and the problem went away.

I would advise you to polish the feed ramp really good and make sure there isn't anything interfering with the slide travel, and make sure your mags aren't catching the magazine.

I don't think it is limp wristing. Usually when my wife limp wrists her Glock she gets a stovepipe.

ps.

I don't think it is a problem with Glocks. I had a Sig P229 that wouldn't feed anything you put in it with any magazine you used. And I also had a USP40 that wouldn't go into battery everytime and it was brand new. I used to have to slap the back of the slide to get it to close fully.

Sometimes you just get a lemon.
 
**Sitting here trying to bite my tongue.**

The shooter is an integral part of the equation. If the slide doesn't have something fairly sturdy to recoil against, it ain't gonna feed. Period.

Now, we don't know specifically that that's what's causing this particular malfunction. We still don't know enough.

...but anyone that says that limp wristing isn't a valid cause of failures doesn't understand the dynamics of firing a handgun.
 
I've seen several cases of "limp-wristing", but this really doesn't sound like one; is the pistol new (3rd gen) or used (1st or 2nd gen), and has it got up-to-date parts? It sounds like the recoil spring might be going on you, if it'll EJECT the round you fire, but won't fully FEED the next one in the mag. (The "limp-wrist" cases I'm familiar with usually end up with a stove-pipe jam caught between the slide and the barrel hood, and no new round in the chamber.)
 
Really?

You would think that being a mechanical engineer and having about 15 years of practical experience with semiautomatic pistols would have taught me the "dynamics of firing a handgun." Gosh!

Granted that the recoiling mass must have something to provide resistance, and that the shooter may absorb some amount of the energy of the recoiling mass -- varying amounts, even, depending on how it's held. But does ANYONE know that the slide isn't reaching it's full rearward travel in this case? What makes you think so? The short-stroking theory is just that, a theory. And I don't think that happens in a pistol that remains in the shooter's hand, at least not with a stock recoil spring. If anyone has evidence to the contrary, I'll be happy to admit my mistake.

The "you're holding it wrong" argument is just a cover used by lazy manufacturers to shift the blame elsewhere for their design problems. Would you buy a wristwatch that wouldn't keep time if you were "wearing it wrong?"

But we are not helping the original poster with this debate, are we? I say have an experienced shooter try it (apparently already done) -- what then, if it keeps malfunctioning (apparently it has)? I say return it to Glock under warranty.
