Yeah, you must be riding the slide with practice rounds, but have a proper grip with self-defense/duty ammo.....rolls eyes | |||

Any of my Glocks will digest anything. You might try downloading the magazine one or two rounds, especially if they're new. Leave the mags loaded for a few weeks. If there's really strong spring pressure, the rounds in the magazine may be lowering slide velocity. | |||

I had a Glock 43 that did exactly what you were describing. Didn't matter the round. Glock sent me a new extractor and a new RSA and it fixed it up. On a side note, when I first shot my 43x, super light 115 grain FMJ ammo would go into battery a bit slower than it should. It did this on the first 30-40 rounds, but never did I have to push the slide forward. At the 50 round mark, it went away. Never did fail, but it was tight. I put more lube on the rails and barrel hood and then ran another 250 just fine. | |||

What’s the plunk test? Checking chamber fit by hand with each round? | |||

Is your "practice ammo" some no-name remanufactured stuff? I'm always somewhat suspicious of functioning problems when no ammo brand name is mentioned. | |||

Sellier and Bellot and one other brand but I'm not sure what it is. It is all factory new. I have a hodge podge of different kinds of ammo because I buy what I can find cheap. I have some federal I'll run through it after it's lubed up good. | |||

Probably the cheap no name ammunition. | |||

This is a good post. Simply put if a gun doesn’t run it’s JUNK. No reason to put up with a gun that should run but doesn’t. Glocks are good guns.....except this one so far. Remember, this is all supposed to be for fun................... | |||

Yes. Verify that the practice ammo "fits" the chamber. I had 4 boxes of "good" fmj ammo, and ended up checking damn near 200 rounds. 100 failed to seat in the chamber. They physically appeared identical in OAL. They all fired in a different pistol. Never had the issue again, but never bought that brand again. If you're goin' through hell, keep on going. Don't slow down. If you're scared don't show it. You might get out before the devil even knows you're there. NRA ENDOWMENT LIFE MEMBER | |||

I’ve addressed this twice now. It’s not no name ammo. | |||

Have you had anyone else shoot it? Any possibility you are limp writing it somehow? Could make the difference in slide velocity? | |||
|
| Member |
I may be able to shoot it tomorrow. If so I will have someone else try it out. | |||

Is the breechface free of burrs and smooth? I usually run the Win 124 NATO loads thru mine to smooth out a new gun. | |||

I’ll double check that. I shot it yesterday and I had no issues. I oiled it good and ran a mixture of the same S&B, some American Eagle, and magtech FMJs through it. All fires fine with no issues. I’m wondering if the gun and mags were just real tight and that, along with not being properly lubed, were causing my issues. | |||

I am having a similar problem with my G43X while using weak Federal 115 gr ammo. I have had an occasional type 2 malfunction and the slide fails to lock back on the last round sometimes. Runs great on defense ammo and 124 gr NATO rounds. The more NATO rounds that I run through it the better it operates on weak ammo so I think I just have a tight gun/ recoil spring assembly. The wife’s 43x has ran great on any ammo that we put through it. | |||

American ammo can be down loaded. Basically bunny fart loads. On every new gun I break in, I LUBRICATE the gun and break it in with 200 rounds of 9mm NATO or other plus P ammo I have. And the first 50 rounds I shoot out of almost any new gun is going to be Federal 9BPLE 115 +p+. The hotter self defense loads work fine, which tells us your gun is new and prefers some hotter ammo, at least initially as the springs break in. 1) use hotter ammo for the first couple of rounds 2) European ammo loaded to CIP standards are usually hotter than American SAAMI stuff. Find some 9mm NATO or Italian Fiochi to shoot. 3) store the gun at home when you are not using it, with the slide locked back. This will help break in your strong recoil spring. I guarantee that if you go run 100 rounds of +p duty ammo through it, the gun will run perfectly. So is it broken, or just in need of more breaking in? I vote that it needs broke in. Glock has a LONG history of using overly strong springs in their guns, that require break in. Wal-Mart sells 150 rounds of 9MM NATO for $27.xx. Stock up at that price. The stuff is quality, and hot, and runs good. ______________________________________________________ Often times a very small man can cast a very large shadow | |||

It could've been something as simply as needing a little break in period, or to be lubed better, or possibly you were limp wristing it the first time. If it runs 500 rounds without issue, I'd say it's GTG. | |||
