One of Batman's most defining qualities is the fact that he despises guns. This is obviously down to the way his parents were murdered in Crime Alley when he was a youngster, but for a time, the Caped Crusader had no problem with arming himself with a six-gun during his patrols. During his early appearances, Batman was more of a crime fighting Sherlock Holmes than the superhero he's since become, so being equipped with a firearm made a certain amount of sense. It was something which didn't last for very long though as creator Bob Kane later said that the character carrying a gun just didn't "feel right" to him.
