I've never even heard of Gangster Squad. I will agree that the lack of reloads takes me out of a movie. There was one my friends & I saw back in college with two guys blazing away at one another. Each had a revolver and the fight went on seemingly forever, with both guys running through some fort or warehouse or something. At one point, one of the guys was even doing the super-fast cowboy method of firing a revolver, as in hold it in one hand and swat at the hammer with the other. Neither reloaded and each fired at least 16,827 times. They ended up facing one another. I think the good guy had dropped his gun. The bad guy gave his smarmy bad guy speech, raised his revolver, pulled the trigger and...click! The good guy, of course, didn't flinch and told the bad guy he'd been counting bullets, then reached down, grabbed his gun and shot the bad guy. It was one of those times I got very angry at a movie and would have thrown the projector if I'd been able.
