I have noticed that most every picture I see of a 1911 the hammer is back. Why is this? Does this have something to do with the Safety? I have never had an auto loader like a 1911 but I do have a Springfield XD in .40 cal. My XD I keep a snap cap installed to limit the amount of tension I leave on the springs. Can you explain to me why the Pictures I see, have the hammer back in the cocked position? Thanks
