Hi guys, I am going to be setting up my Glock 21SF for occasional shooting of .45 Super loads. I'll be going with a T.H.E. SS guide rod and 22lb. ISMI spring, a Lone Wolf barrel, with the supported chamber and of course, .45 Super brass from midway. My question, is a recoil buffer a necessity or an optional extra that would help to keep the frame from being battered more with the hotter .45 Super loads? Thanks.
