I don’t think I’m gripping differently… support hand thumb is definitely touching the slide. Ejector on gun with problems is gen 5 47021, on G17 is gen 3 336.

I compared it to the extractor in my 17, nothing jumps out at me. New extractor & depressor spring?

At a loss troubleshooting gen 3 G34. She’s been running no problem, for about 2 years, 20k+ rounds, LOTS of dryfire. Couldn’t get through a stage last Saturday without multiple malfunctions. Mostly, failure to feed. (Gun goes off, round ejects, double feed on next round, sometimes a weird “horizontal” stove pipe) Stock (brand new) recoil spring, stock everything, overwatch precision trigger shoe, relatively new oem mags, factory Fiocchi 115. Just wouldn’t run. Swapped to 13lbs glockstore heavy tungsten rod and taran’s striker spring. Sent 40 rounds into the dirt in between stages, seemed to run fine. Next stage, same malfunctions, went home. Today, tried to isolate. I was leaning towards mags. All mags run 100% in a 17 and a 19. Same ammo. Same exact issues today in the 34. Started bone stock, same type of malfs. Went to 13lbs spring and reduced striker spring, same. About 60 rounds. (Ammo and mags run fine in my other 2 Glocks). But then, the really weird thing. I swapped frames between 17&34, ran fine. Swapped back (final config: original frame&slide, 13lbs spring, taran striker spring) and for the next 150+ rounds, no issues. Which leaves me at a loss…I don’t think it’s the mags but I don’t understand what the problem is, really. Anyone care to chime in and point me in the right direction? Appreciate yall.

I’d trade problems! That sometimes happens to me on Glocks. Put 150 rounds through her today focusing on gripping lower. Still happened every so often but doing better. I really have to cant my support wrist and point my thumb forward.

M9 with LTT slide.It seems that if I grip the gun anything like I would a Glock, I’m interfering with the slide lock lever, and the slide locks open. It’s really touchy, like if I’m anywhere NEAR the damn lever, this happens. I see videos of folks using a similar thumbs forward high grip as mine and running the gun with no problems.Love the gun and how it shoots but this is obviously a major issue for me.Do i have to re-learn a new grip?Has anyone else experienced this or has any insight?Thank you very much! https://youtu.be/6pfyold_m38
