A dirty gun can get you killed. If you conceal carry and fail to run your gun clean it might back-fire on you, literally. We had several malfunction on the Kahr cw45 because of an unclean gun and ammo that fouled the gun even worse. Also, the Kahr is finicky, if you don't load the first round as directed (using the slide release to load a round), it might not go into battery properly. Keep your gun clean and it will serve you well, plus, a good gunsmith is worth his salt.
