I don't use them in any of my pistols, I have had bad luck with them . Kenn Tapp, big name pistol shooter, does not use them.
They break at the wrong times which ties up the pistol until it can be taken apart and the pieces of the buff removed. Some say, change the buffs every so many rounds (that number depends on who is giving the advise) and there will be no breakage problem. I have seen new buffs become little bitty pieces on the first magazine fired. I am talking about brand name buffs not the ones produced by Uncle Fred using his hand held punch in his garage.
I also think that, if not thinned width wise, they exert lateral pressure on the frame under recoil. I can not help but think that such pressures can not be doing any good to the frame.
My opinions only, others will have their opinions regarding the subject. BTW, I think this was covered sometime in the past along with the full length guide rod question.
How did pistols exist for all those years without the Shock-Buffs? LOL
