I’ve a gen4 G34, the slide doesn’t lock back after the last round.
- thoroughly disassembled & ultrasonically cleaned
- 124g handloads with 7.0g of AA7 or 147g Win white box.
- 2 new gen5, 1 gen4 and a Magpul mag.
- When the slide’s pulled back it’ll lock.
Slide release spring weak?

Other than that it’s slick as bat guano
 
Most likely your thumb is riding the slide release and holding it down. You would need somebody to watch you shoot to tell because your grip might start out fine but shift under recoil.

Or shoot it one-handed, strong and support.

Mine did this too until I changed my thumb position. If you try to ride it along the slide like a 1911, it's never going to lock back especially with the factory extended slide release.

My gut response, “no way, I’m paying attention!”, plus I did fire it rt handed.
I just gripped it and it looks like I missed the obvious. o_O
It’s never happened in 25+ yrs with any of my other glocks.
I’ll try a std slide release as a test and stop shooting alone.
Thx!!

I don't consider Glocks perfect, but I do like them a lot. I used to shoot IDPA regularly and always did my best with a Glock 34.

've still got two Glocks, a 37 and a 38, and I upgraded the 37 with an Apex trigger system, which was really a big improvement. My 38, wich is a bedside gun, has a Ghost trigger mod (upgrade?).

I consider stock Glock triggers okay, but as it the case with many striker-fired guns (other brands, etc.) they are generally only so-so, and nothing like the best hammer-fired gun triggers.

I also have a .40 conversion barrel for the 37, in case .45 GAP is ever hard to find. It's from Apex Tactical. They send along an extra ejector for when you use the .40 barrel, but I've found that it works fine with the .40 ejector when using either caliber; it would probably work with the stock .45 GAP ejector, too.

Is the slide latch spring leg on the correct of the PIN? My brain tells me it goes underneath but I'm not looking at my glock right now
 
I just went through something similar on my g23 on sunday. I put in a new slide stop and spring and wholly hell! it was doing all kinds of wonky stuff. would not lock back on empty mag, then I couldn't sling shot it to load a round, but it would load fine if I used the slide stop to release it. I checked all my mags, went crazy for a few minutes, then I took the slide stop out, reinstalled the slide stop with the little tail under the pin/ block and boom! no more problems.
 
Silly question, did you install the top pin first then slide the slide stop in and then the second pin.

Years ago I had slide lock issues because I installed the slide sto and bottom pin first then the top pin, the gun would do a couple of things depending on the situation, it would either lock back after every round I fired or it wouldn’t lock back on the last round.

I pulled it out yesterday, the slide stop/release is installed correctly.
Shot @ 80 rounds trying to find a grip where I wouldn’t touch the extended stop/release. Did a quick YT/interweb search for best grip styles with it and came up blank.
It’s gotta go, in 30+ years of 4 other Blocks this hasn’t happened.
 
What? You've triggered half the forum just by saying Glocks not perfect....eh I ain't a fan anyway, just found it giggleworthy.

Keep it. Take the two pins out from the right side of the gun. When reinstalling them slide stop side first. I cannot remember which one is first but it is critical they go back in the right order with the spring catch identified under. This is going to mostly fix the issue. How do I know? Been there, done that. When I have time to find a good video I will link it. Glocks are still ugly as hell but Perfection.

Perfection, I don't think that word means what most think it means. Reliable as all hell for the most part sure, functional sure, a get it done in most any situation sure. But perfection? Nah, they fail, their ergonomics are pretty shitty to be honest, priced as high or higher than any comparable or better polymer gun and come with the cheapest set of plastic sights that could be created by man, amongst other things...perfection? Come on now. All guns fail, it is what it is.

I've never had an issue with the standard OEM slide release. You going to swap it out for the original part?

Bob Vogel's grip technique really does work:

Well, I’m a CZ fanboy. We use the word devine.

I believe it is the original part, and it’d be fine if my thumb was 1/4” shorter.
Me thinks I’ll install a standard release from another Glock and try it.
