I have a Gen 3 G-23 and I have had this problem almost from day one. When I fire 50-60 rounds I used to get a blood blister on the lower part of the pad of my trigger finger. I was able to solve that by shaving some off the inside of the trigger guard and then some off the trigger bottom tip. The remaining problem is that the trigger safety blade seems to irritate my trigger finger pad almost as if it were rebounding after each shot. I'm a big boy and can stand a little discomfort but I would rather not. Am I the only one with this problem?
