I have a colt 1991A1 that I showed to a friend today (after unloading it ofcourse) and he proceeded to let the slide slam closed on an empty chamber twice and dry fired it once,afterwhich I took it from him and told him sternly not to to this to my gun. My question is is it likely that this damaged my gun at all? I know I might be a bit anal here but I don't trat my guns like this and don't like it when others do. Needless to say he won't be handling my guns any time soon again I thought he had more sense than this but I'am still pretty heated over it.
