Hi! I use the lone wolf conversion barrel to shoot 9mm with my glock 23. Initially I had issues with fte and ftf using the glock 17 magazine and shooting Winchester white box 115 grain ammo. I ran a box of +p ammo, and that seemed to clear up the problems with running the g-17 mags. Now when I use the Glock 33 round magazines (using white box 115 ammo and other brand name 115 grain ammo), I still have fte, ftf, and stovepipes as well. Any recommendations? Can it be the 33 mag springs? Also, I dont know if this is important, but I have the Tungsten guide rod, maybe the additional weight affecting it somehow? Thanks!
