I have searched quite a bit about the subject of what handguns can and cannot be used with 45 super. The XD and HK are the two that come up being able to shoot them in moderation right out of the box without modifications. I keep noticing, however, the thought that it needs to at least be a 4" barrel. I've thought about the XDm compact that has a 3.8" barrel. Is there a reason I keep seeing that it needs to be 4"?
