atbarr Posted December 9, 2012 Share Posted December 9, 2012 (edited) Hello people, I purchased a G1SF to shoot Production. With a PF of 150 my brass falls at my feet. I'm using a 14 lb. recoil spring. I'd like to get the PF down around 140 PF. What lb. recoil spring do you recommenced, so the brass falls a few feet from me? I did a search for 'G21 + minor' and received no links. Help please. Edited December 9, 2012 by atbarr Link to comment Share on other sites More sharing options...
EkuJustice Posted December 9, 2012 Share Posted December 9, 2012 Try a 13. I would be a little worried going lighter as I am not sure the 11 would have enough power to pass the slide test. I have both the 13 and 11 for my open glock if you want to give them a try sometime AT Link to comment Share on other sites More sharing options...
