I searched the forum and couldn't find anything related to shock buffers .............. so here's my question. Has anyone had any experience with shock buffers specifically designated for a shorter barreled 1911? I was happily surprised when I found that my Colt Rail Gun had a shock buffer installed when I got it from a friend and upon firing it I noticed a significant reduction in felt recoil (although it could have been helped by the stiffer springs my friend had installed)! I looked in my Brownell's catalog and found several manufacturers that make the shock buffers but no mention of any of them being different between a full size, Commander size, or Officer size barrel. There didn't seem to be any distinction regarding barrel size. The Defender 1911 (3") doesn't (to me) seem to be difficult to control but I'd like to try a shock buffer to see if it would reduce the felt recoil (and they are pretty cheap). Any information would be greatly appreciated, especially from someone who has used them on a shorter barreled pistol ( 1911 or other). Thanks.
