Dunno about how they do things in the States, but erm, that's the general idea here.
Thing is though, after 20 seconds of 'A gun! Great! Ain't I the big badass!' a couple of things start to become apparant once the intial novelty has worn off.
They become heavy, they chafe your shoulder, they have to be cleaned, you call it a 'gun' at your peril. (It's a rifle!)
After a couple of weekend exercises I just saw them as any other tool - a 5kg lump of plastic and metal.
Antique firearms and their history are far more interesting.
