Glock 23 cycling problem with modern JHPs

[savasyn]

I have a G23 as an HD gun. I currently keep it loaded with older Pro Load 135gr JHPs as they have proven to cycle reliably.

I've tested both 185gr Speer Gold Dot and Federal HST rounds and both have failures to feed somewhere around the 5th-7th round. The nose of the round is tilted down slightly wedging it into the front of the magazine. Pulling lightly back on the slide allows it to pop up and keep going.

This happens at least once, if not twice per mag load. I'm now using a newly rebuilt 13 rounder but the same thing was happening on the original one.

Only changes to the gun are that I put in a Glockmeister steel guide rod with stock weight spring and there is a TLR-1 mounted on the rail.

It seems to be a length issue, the 135grs have a slightly shorter overall length than the 185grs thus allowing them to clear.

This G23 and mag will cycle 180gr FMJs all day long without a hiccup.

Anyone else have this problem or any ideas on how to fix it? I'd like to move to the newer, heavier rounds but obviously won't until they work 100%.

Thanks!

I seem to remember a LEA having issues when a light was mounted. I'll look for it and post if I can find it.

I had cycling problems with mine when the laser was on to tight. As soon as i loosend it a bit, the problem was gone.

Yup, that exactly describes my problem. I've only tried a 10 rounder once with JHPs and, IIRC, it functioned correctly. I may have to retest in the current configuration with 10 rounders. WHile I'm not thrilled about losing 3 rounds, having a gun that runs 100% of the time more than makes up for it.

Weird that it only happens on the .40 models. I guess it's a function of the way it recoils or something.

+1 on mounted light problem. This is why they are coming up with redesigned G22(Gen 4. RTF frame is not gen. 4)

The explanations I heard is that having extra weight prevents the frame from flexing, which allows slide to move faster than the magazine spring pushing up the round.

Call Glock and tell them your problem. They might have updated mag followers to correct your problem.

My G19 mags came with the old follower so I called Glock and they sent me the new followers and it works 100% with the widest hollow point I know of which is the Cordon DPX load.

I'll give it a shot, but I think I have the latest design in the current mag.

I believe that GLOCK's solution was a different magazine spring which added 1 coil. I also believe that once you change the spring in the mag that you should only fire this weapon now with the light mounted. I thoughly range tested my G22 that is mounted with a TLR-1 and had zero problems. I have read that the problems seem to vary from gun to gun. Correct in that it mostly a problem with the .40 guns, G22 and G23.

My stock G23 eats EVERYTHING. It really loves Winchester Rangers JHPs. Maybe you can give me some of your JHPs and see if mine can eat them.

Sounds like a +10% Wolff mag spring should do the trick.

My thoughts exactly. However, this is a widespread Glock 40 problem. Should be a factory fix avail.

Honestly, try bringing it back to the stock configuration and see if the problem persists (I doubt it will). Then go from there. Any time you modify anything you're inviting in trouble.

You know that's what my wife keeps telling me when I bring one of my guns to the garage to tinker with.

I'll certainly drop the stock guide rod back in, but the whole point of buying this particular gun was that it needed to carry a light. My previous G23 didn't have a rail.

I'll see about getting a stiffer mag spring first though, as that's easy to test.

I just ordered +10% Wolff mag springs as well as one of the new, lighter TRL3 lights. Maybe some combination of all that stuff will work.
