Got BOTH my Pachmayr Gripper grips for my Pitbull and Bulldog. Put them both on. First impression....WOW! They feel MUCH better than the factory rubber grips. And the grips fill my hand much better and are a softer rubber than the factory ones. Squeezing the trigger double action also requires less effort and is more comfortable. I'll post feedback on actually shooting with them when I get the chance.
