Pearce +0 grip/ magazine extenders - Pearce Grip PG19 For Glock Mid & Full Size All Calibers Grip Extension Black Finish

These are great. I put these on all my compacts and subcompacts and they completely change the fit of each gun to my hand. They improve accuracy, control and comfort for me. They may print a bit more but it's such a small difference that if it's what's makes "the difference,"I probably should have changed my shirt anyway to be safe.
