Beretta 92 LTT slide not locking back on empty mag consistently after changing sight

[The Dumb Gun Collector]

I need some of you Beretta wizards to help me out...

I had the front fiber optic site changed out with a tritium front sight at a shop that has always done a pretty good job. when I got home inserted an empty magazine and I noticed that the slide did not lock back. I figured well this mag must be at the end of its days so I opened it up stretch the magazine spring out and sure enough it locked back. I assume that my problem is solved but then when I went home I tried several other empty magazines and none of them would lock it back unless i pulled the slide very firmly and fast to the back. I have two other Beretta 92s one with many thousands of rounds through it and neither of them exhibit this behavior. The gun only had 50 rounds through it before I dropped it off but I do not recall this before. Ideas?

Can’t imagine they did anything with the frame, but have you checked the slide stop spring to make sure it is GTG? Guide rod and spring installed correctly?

That function is solely on the magazine follower and the slide stop. I think the slide stop spring may be the culprit. You may want it inspect for debris in the mag body.

Did you hand over the entire gun to the shop or just the slide?

Greg, not sure if I missed in the OP, but what mags? Try factory 17rnd mags.

Only you can manage to have some local yokel shade tree parts changer screw up a finely built custom gun. Since it's broke now, I'll give you $450 for it.

I think it is a bunch of nothing. I swapped out the slide lever from another Beretta I have and it worked consistently. Then when I put the original back on it worked better. But I took it out and shot 50 rounds with the weakest mags I have and there is no issue. I think it is just knit-pickery on my part but I will keep you posted.

Greg,

If you still have issues with it, try a replacement slide stop spring. I bought some from Brownells here. They are fast to change out and having a few extra in your parts box never hurts. Failing that you can always send it in to Ernest. His shop does amazing work and has fast turn around times for smaller jobs.

Y'all ignore my dumb ass. I took your advice and broke out some of my non beater Beretta mags and the thing sprung up and locked like it was on Viagra at the Dallas Cowboy's cheerleader camp. Basically, any new mag, sand resistant, 15/17 rounder, 20 round Mec-gars, etc all pushed it up super fast under any circumstances.

Anybody who knows me knows I have been shooting the living crap out of my Beretta 92G-SD for years and I basically use the same 3-5 mags until they fail. These have never failed but they clearly need new springs.

I have an M9A3 modified by LTT with trigger work and an RMR. It quickly became a favorite pistol of mine.

Glad to hear nothing was wrong with the gun but I will still give you $455 for it. I’m not a low baller like Sam!
