My main issue with the Bighorn (plunger style hammer) is that My thumb keeps getting hit by the plunge during recoil. Have any of you ever had this issue? I have a bloody gouge. I don't see how to keep my thumb enough under it to not get hit, nor off to the side where I won't get hit but my grip will suck. Every time my thumb gets hit and opened up again the thumbhole stocks look more attractive.
