I was attempting to install an extended slide lock release lever on my 19. While trying to pound out the pin that holds it in the frane the punch slipped and I drove it into the slot just below the take down release leaving a round punch hole in the same area. Slide release levers work fine and slide comes off with no prob. It just looks buggered up. As it widened the slot just below the left take down release into a round whole, I suppose there is no way to restore the polymere back back to the way it was ???
