Howdy guys, I'm new to the 1911 scene. On a MK IV Series 80 is it safe to carry with the hammer down with a live one in the chamber? I know this may not be the preferred way for many, just curious about the safety factor. Thanks in advance for your help!
It's safe in theory because the firing pin can't contact the primer unless the trigger is pulled. The unsafe component of the equation is safely lowering the hammer on a live round, not a preferred action for most people. The 80 series safety system was, I believe, concocted to prevent AD's if the loaded pistol was accidentally dropped on the hammer. I'll now get out of the way and let other 1911'ers present their views.
I'm no 1911 expert, but like asa said it's a matter of lowering the hammer down without it going off. I wouldn't do it. The only time I pull the trigger is when it's unloaded or on target. Other than that it's too risky.
