I use the Wilson shock buffs in a lot of my 1911's for practice. Especially the Delta Elite, .460 Rowlands and Lightweight Commanders . Using them and the lightest recoil springs that work in that gun is being nice to your prized piece. You do not need to hotrod your loads. No reason at all to do that.
Do not use the shock buffs in your CC guns. They can cause problems if they tear and jam things up. They are cheap and last longer than you would think. But inspect them every time you clean your gun.
