I was in the process of cleaning my Ruger SR9, when a buddy decided to drop by for a drink. he noticed my SR9 on the counter and snatched it up. He asked if he could dry fire it, and against my better judgement i told him he could. Im not too big on my nice firearms being dry fired, but once in a while wont hurt i figured. After dry firing the SR9 he kept the trigger recessed, depressed the slide stop lever and half cocked the firearm. with the slide not even completely forward he attempted to dry fire it again. I quickly snatched my gun and told him how big of an idiot he was for whatever the hell it was he was doing. I almost had a heart attack. im very passionate about my firearms and only want them used correctly. i assume what he is doing is incorrect and could possibly damage the internals on my gun. Am i wrong to thing you should not treat a firearm this way?
