"Sig209" is right - One must mark each mag - in my opinion - so that an out-lier can be identified.
Was sighting in a Ruger 22/45 Lite and had several FTE, and FTL. Tried several other 22LR with same result. Then (duh) it occurred to me that I was using the same mag. Tried five other mag with no issues. It happens.

Yes I always number my magazines with silver sharpie. That particular magazine will get a serious workout. I've got two more coming for a total of 4 so worse case I use that one for range use only for peace of mind.

It cleared very easily.

Anyone else notice maybe with the slide off, that when you insert a loaded mag in the frame that the ejector pushes down pretty far onto the back of the top bullet? Maybe that had something to do with it.

I love the Glock 43, but I wonder if I have had more issues.

In fact, we love them so much we have 5. I do the testing of our favorite carry load, Federal BPLE 115 grain +P+. (Favorite partly because it is cheap enough to play with snd test a lot.)

Out of about 1400 BPLE rounds, I have had one malfunction in each of three of the five guns. IE, 3 malfunctions in 1400 rounds. They occurred at approximately round #160 in one gun, #14 in the second, and #42 in the third. For each gun, I have at least 200 more malfunction free rounds afterwards. I have lots of magazines, and like an idiot, I do not know if this was one, two, or three different magazines. (Don't ask.)

Never any issues with FMJ, and haven't yet jumped into other favorite carry load, Federal HST 147 grain.

Interestingly, I just tried the other day a Pearce +1 extension, shooting again BPLE, as I was finishing up at the range, and got a failure to fully seat into chamber on round #5. Grrrr. Haven't tried more yet, but will. Haven't checked back to ensure I put the baseplate on correctly.

Is my experience different from most others?

I had the same exact issues with mine but I'm running the pearce +1 extension, failure to feed on the last round over 50 percent of the time, I thought maybe I was limp wristing but only on the last round doesn't make since.
It looks like maybe the slide didn't retract fully wish now I would have paid more attention to it and took some pictures going out again Sunday and try some more.

I have Pearce +1 baseplates on each mag, no issues at all.

Fired 75rds of fmj today it continues to be 100% with them. My #1 magazine had the oem grip extension on it, I replaced it with a Pearce +1 extension and liked it very much. After a few hundred more rounds I'll revisit the gold dots.

Replace the magazine spring.

It is mechanical, there will be failures. As long as it isnt something drastic like every mag, once in a while is fine. I have probably close to 2000 rounds through my G43 with probably half a dozen failures....could be ammo, shooter, gun, dont know but tap, rack, bang fixed it every time. I dont even spend half a second looking at the issue, I go right into the malfunction drill. Now if that doesnt fix it, then there is a problem. Anyway, my two cents.

Another 75rds of fmj without issue. Decided to try a mag of gold dots and again it choked on the last round. Identical malfunction to last time. Stopped the slide just out of battery. The bullet is fully seated in the magazine still. Had to clear it since someone wanted to call cold range so I did the glock grip like to dissasemble it then dropped the mag. Was a different magazine this time also. Shot some more fmj before I went home.

This is what the bullet looks like.



Hard for me to relax only because I have high standards for my firearms. My Sigs have been 100% as well as the XDs I've owned and even my new SR22 has been perfect.

Only variable I can see is the faster slide velocity of the hotter ammo causing the slide to outrun the mag spring especially since its on the last round that it's happening so if that's the case...stiffer recoil spring or mag spring or?

I fired several mags of the 124gr +P short barrel Gold Dots (23611) when I first got my 43 and never had any problems.

If it's happening with multiple magazines, I'd have Glock look at the pistol.

I have had 3 brand new 43's do this exact thing this year.

And how is it that you have access to all those G43s?

I bought one in February and it jammed the first day. I brought it back to the gun shop and he gave me another brand new one. That one jammed as well. They were both current production models made in January 2017. He then ordered me a 3rd new one from a different supplier. This one has been better but it will still jam occasionally with hot ammo on the last round with both magazines.

Hmmm..

My next easiest thought is try some standard power gold dots but I've got 200rds of the +p stuff in the closet already and we all know how much this stuff costs..

It's gotta be you and not the guns.

3 in a row?

You're limpwristing it or something and don't realize it.

That's what I thought too but it has happened with everyone that shot these guns with me. Also I have found a few posts from different people with current manufactured 43's that are jamming on the last round with high powered ammo. I think it may be a problem with the magazine spring or recoil spring weight.

My +p theory doesn't hold water. Went to LGS and bought a box of standard 115gr gold dots and on the first magazine had a worse version of this malfunction. Slide rode over the last round and then dragged it forward into the feed ramp, holding the slide out of battery.

I also shot an entire box (old box at least 15yrs old) of Federal 147gr hydra shocks without issue.

Tomorrow I'm taking it to my LGS that I bought it from he carries a G43 with +p Hornady and he's gonna try it out with me.

So I guess you're having this problem only with +P. Could be the heavy recoil of the +P is jarring the round slightly out of position since the last round has the least spring tension on it, and is pushed by the follower rather than a round. That of course is just a guess. If it's also happening with standard pressure JHP, then of course this theory does not apply and might be a feed issue with the hollow point.

FWIW, I shot only one or two mags of +P ammo through mine and I don't recall such failures. The only such issues I had was with +1 mags and that wasn't limited to JHP or +P. That was early on and it seems to have worked it's way out. I don't however carry with the +1 mags just for this reason.
