I recently watched a film called The International, starring Clive Owen. There is a prolonged shootout scene that takes place in the Guggenheim museum in New York. At the start of the shootout, a New York detective is shot, and Mr. Owen, who is unarmed at the beginning of the fight, recovers his gun, a .357 K frame snub. He then proceeds to fire five rounds at one bad guy, retreats behind concealment, and fires seven rounds in a continuous string at another bad guy. He then picks up a Steyr submachinegun and fires infinity rounds, reloads once, and fires another infinity rounds. He is accompanied by another bad guy, now an ally, who fires infinity rounds from a Glock. All the really bad guys have more of those Steyr subguns with their infinity magazines. At least they shoot the hell out of the Guggenheim, which deserves it.
