Failure to Feed in Glock 19: Any Thoughts?

My wife and I had a couple of failures to feed in my Glock 19 during the 200 round FMJ (WW Whitebox) break-in, then again a couple of times in the 200 round JHP (Federal 9BP) break-in.

Since then, it exhibited no problems in hunreds of rounds both FMJ and JHP. Recently, however, I tried American Ammunition (packaged in transparent plastic) and I had it happen a couple of times again.

It always happens this way: with one round remaining in the magazine, the slide locks back and does not strip the remaining round from the magazine, resulting in a stoppage.

What could be causing it? My theories are:

1. Simple limp-wristing (never on other handguns, but maybe the Glock is light and polymer, so...).

2. Bad magazine.

3. Bad luck: simple break-in jams earlier on with FMJs and JHPs plus bad ammo (American Ammunition) later on.

4. Something intrincally wrong with the gun.

Any thoughts or comments? Thanks.

Bad gun, I'll take it off your hand for $200. You keep the magazine. Hee Hee.
Just kidding, try different magazines or have other people shoot it.
 
Actually, you might find that an attentive eye to your thumb position will resolve the 'malfunctions' that you mention. My G19 and my wife's G19 have been purposefully 'sabotaged' by a 1911-loving-friend that likes to make it look like the Glocks are problematic.

He does this by using a 'thumbs-high' shooting position and pushing up on the slide release in the middle of a full magazine. His quizzical looks about the gun's 'malfunction' are easily investigated. I take the gun and fire off the rest of the magazine without any problems.

If you're a thumbs-high shooter, try with thumbs-out or thumbs-in and see if that changes your problem. The Glock Factory magazines that I have do not cause problems, IME. Aftermarket mags are notorious for various problems.

Also, check the tension of your slide-lock-lever when you disassemble the gun by pulling up *slighly* on the slide-lock-lever with your strong side thumb. It should 'click' back into place - if it doesn't, the spring has become misseated (rarity) or is missing (even more rare). Good luck,

Long Duck may have something, but I'd take a look at the magazine first. BTW, did it happen only with ONE magazine or multiple? If more than one, more likely NOT a magazine unless you have the incredibly bad luck to have more than one mag with bad springs.

Good luck!

I had a problem with the slide locking back with ammo in the magazine while shooting my G35. It was suggested my thumbs high grip was causing me to bump the slide stop.I took the extended slide stop off and the problem vanished.

Then I got a G27 and the problem came back. I "choke up" on the grip as far as I can since the grip is so short. I hit the slide stop once in awhile with my right thumb. Started placing my right thumb low on my left thumb. Problem is all gone now.

Of course, your problem could be something else altogether.
 
The 9mm 10-round mag flat followers simply suck. If this is what you have then this is probably the problem. You can order new followers from various sources but specify that you want the HI-CAP 9mm followers that are marked 9mm3 these are the newest design an work very well. These were rumored to cure a this problem because Glock had changed the feed angle on the newer Glock 19s (the finger groove and rail models) so that its barrel cams at the same angle as a Glock 17. Previously the 19 and the 26 had the same angle but the 17 was less steep These are completely legal to use in the 10 round mags and do not increase the capacity in any way. You can order them from glockmeister.com or get them from any certified Glock Armorer (they usually cost about $2-3 ea.) on the glockmeister.com site he calls them LE followers (Law Enforcement) under 'stock parts listing' but do specify you want the 9mm3.

Your Glock is probably just fine. I know three different people who have had problems with American Ammunition in the last three months. All three had numerous malfunctions. Two were with Glock 19's in 9mm. The other was with a Sig P220 in 45 ACP. The cases are not sized to the proper dimensions. If you have any of that ammo left, here is a simple test. Take the barrel out of your 19 and see how those rounds fit in the chamber. They should smoothly drop in and out of your barrel. I think you will find about one in five rounds are to large for your chamber. Try this with another brand of ammo and you will see what I mean.
The cheapest ammo is not always the best deal. Try something other than American Ammunition and you won't have any problems.
 
I am the P220 owner mentioned in henryb's above post.

Stay away from the American Ammunition.

See my story somewhere in this thread:

The Glock 19 is my duty weapon and I prob have about 5000-7000 rounds through it. I have had about half a dozen failures resulting from the canting of the gun using a body bunker. When I instruct I have seen the prob you describe when shooters do not clamp down their strong thumb with their weak one.

I agree with Robb........Try changing the magazine followers. Most of the failure to feed problems I've seen in the G19 were corrected with this simple modification. Call Glock, they'll send you some new followers. BTW, what part # is stamped on the followers? The "9mm3" followers always seemed to work properly.
 
do the followers say 2183-1 on them? i have the same problem with mine. the last round hits the feed ramp and just stops. call glock and ask them to send you 9mm3 followers.
