You don't see those in films much (ever) because it's a breach loading single shot, single action pistol. Not condusive really to the uber shootouts, where they expend 700 rounds and no one even gets hit.
It's a gun used mostly by big game hunters, so it was fitting to have it in this film.
I always thought this was a cool flick.
They make the same or similar one of that gun in airsoft. The manufacturer is Digicon of Japan. They make a 8 & 13 inch Â“TargetÂ” model that uses gas and real shells to hold and shoot the plastic BBs. Apparently, they're pretty powerful... :eek
