My new Federal Arms barrel for my glock 23 in 357 was not very encouraging. Half of the rounds nosedived into the feed ramp. I polished the ramp to a mirror finish over the weekend. If that does not solve the problem I may purchase some glock 32 mags. Any advice? Any similar experiences? Richard P.S. I was not impressed with the supposed muzzle blast & recoil of this round. I was shooting PMC 357 sig FMJ & it was like shooting 9mm in my opinion.
