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.
