I've heard this quite often but am puzzled by what it means. I llike revolvers.I do shoot a couple semi autos (ruger mark II .22 and a springfiled armory .45 auto which I also like very much. I assume locked and loaded refers to semi autos but I still dont get the connection. Neither of my semi autos are ever "locked". If I put rounds in the magazine and shove the magazine in the pistol its not locked nor is it loaded If i pull the slide back and put a shell in the chamber its loaded but still not "locked". If I put the safe on its still not "locked" its just on safe. Is this just a television phrase or does it mean something?
