usmc1974 Posted December 26, 2011 Share Posted December 26, 2011 I was wondering, what makes a SJC barrel strong enough to shoot Major, over other after market barrels like Stromlake or Lonewolf? I had a SJC open glock 17 and It ran great on a PF of 170 (124 jhp and 7.1 grains Autocomp vel 1375 oal 1.133) Quote Link to comment Share on other sites More sharing options...
