I'm having trouble. The rig is a Glock 17 Gen 3 with SJC 11 port comp, along with an SJC C-More mount. Even with 11# springs I'm still getting one out of 10 shells jammed between the slide and the SJC mount. At first I thought it was the recoil spring, but now I don't know what to do. It seems to run fine with hotter ammo and 15# springs, but with minor loads it chokes. What should I be looking at? I'm running 124 berrys over 4.0 Titegroup at 1.10. The load is accurate and comes in at around 137 PF.
Do you think I should look at my extractor?
Thanks for helping out an open Newbie.
