Just picked up a 17 gen 4. shot some 124's and some 147's that were quasi factory reloads and they shot fine. also tried factory 115's and 124's they shot fine as well.
I have fired some older Win Ranger/Black Talon HP in 147gr in my Glock 19 (Gen 4) and function was 100% (as is expected with Glocks). However, the velocity spread ranged from 821-977ft/s.
