A couple of times while practicing, I've worn a layer or two of skin off the base joint of the thumb of my right hand. Apparently, when I draw, the underside of the frame abrades that part when I'm moving to grip the gun. This doesn't happen with my revolvers, 1911, CZ or Beretta. Has anyone else had this problem, and if so, how did you fix it? Thanks!
Chuck, It's hard to diagnos this kind of problem without watching you draw, but I suspect you are coming in low on the grip and sliding your hand into position. Try adjusting your draw so your right hand comes in higher over the gun, then dropping the web of the hand directly into position on the grip. This should reduce or eliminate the problem.
I do the same thing when I practice with my P89. I solved it by slowing down or doing surrender starts.
