That is one sweet hi-power.
If you're a pimp. I like mine just the way FN made it back in '69.
In no way would reckless endangerment fly. If a 1911 goes flying into space, and is a series 80, it cannot discharge. If a series 70, highly doubtful. Someone says he's a cop, demand his ID immediately. File a complaint for this ahole's abusive language. He committed the crime of disorderly conduct, under WA statutes, in his action. Make that clear in your complaint. Even if he was a cop, he cannot break the law.
