Can you help me sir. I have a 1911 SA TRP. When I try to shoot Federal HST 230 gr +P HPs through it sometimes the slide will not go all the way back into battery. Do I go with a heavy spring ( factory on 1911 16# ) or a lighter spring ? And second I have a Glock 32 ( that I carried concealed ) I would like to reduce recoil and muzzle flip ... I want to buy a tungsten guide rod and a wolf spring ... do I go heavier or lighter on the spring ? Thanks and thanks for all the great posts that you do !
