Recently, I could not get either of my Glock 35’s (I have two) to reliably feed the last round of any of my four 140 mm mags. I tried everything to solve the situation: new followers, different mag springs, different recoil springs and weights, different bullets and OAL – but nothing solved it.
Then, by chance, I cut two coils off of my ISMI 13 lbs recoil spring (Joe D on the board runs this trimmed spring and suggested it). They all now run 100%. I also feel that the G35 shots flatter and softer as well.
It’s good to experiment
