I just picked up a Kahr PM-40 and it is a great shooting gun, I have a problem with the safety on the gun however. As you can imagine the gun has a stiff but controllable recoil, the safety gets jammed into my thumb joint and starts to rub the skin off after about 25 rounds or so. I would like to get the safety lever ground/rounded down so I cannot feel it but I am unsure as to the legality of having this done, or if any gunsmith would do it. If I had to use the firearm in a defensive situation and the safety was altered as specified above which would make it pretty much inoperable, would that be held against me? Or would the fact that it is still actually on the gun and technically functional matter? I just got this gun and would hate to sell it because of this but this is a big problem that will keep me from practicing with my carry gun as much as I should. Thanks in advance for any replies I may receive.
