Does anyone know if there is any semi autos that doesn't take an ACP style round. I want something to carry when i'm camping/hiking. The general concensus is that a revolver is the way to go (more reliable and heftier rounds). But I prefer the pack-a-bility of a semi. I was thinking around a .45 but the only thing I can find in a semi is a .40 S&W or a .45 ACP.
