RE: 1911 - How do you carry
1/2 cock on a 1911 is not a safety- its merely a shelf on the hammer to slow it down or stop it if the gun malfunctions and is set off without the trigger being pulled.
Cocked and locked is the prefered way- its perfectly safe even though it goes against what everyone is taught when they were a kid about hammers on revolvers and lever actions, the 1911 is different.
The other way to carry is with the chamber empty and the hammer down.
