cocked and locked 

"Cocked and locked" refers to a method of carrying a pistol, often a 1911 gov't model semiauto, with a round already in the chamber and the hammer cocked back and ready to fire. It is a term coined by police who carry 1911 pistols in this manner. Usually the holster strap is inserted between the hammer and firing pin for safety, which is snapped open when needed for a fast draw. It is actually safe to carry a 1911 model pistol in this way because of the redundant safety mechanisms such as the 1911's grip safety and thumb safety to protect against any accidental discharge until the weapon is on target and the shooter is ready to fire.

I like to carry my 1911 Colt Commander "cocked and locked" in my concealment holster when I go out. I want to be instantly ready for action if I have to draw. Having to rack your slide before firing could potentially get you killed.

Cocked Locked and Ready to Rock

A loaded gun with ammunition or a round in the chamber of the weapon that is cocked and hammer locked (if single action) or ready to be fired by simply pulling the trigger.

Often a carry handgun with a loaded magazine that has been cocked locked and ready to rock. It is ready to fire. If a single action pistol the hammer has been cocked back and locked in place. Only the trigger must be depressed to fire the weapon.

Locked, cocked and ready to rock 

Totally prepared and/or anticipatory for a particular engagement. Generally used in the positive sense, for an event which one looks forward to. More euphonic than similar cocked locked and ready to rock.

"Dude, you still good for that party over at Jay-Jay's?"

"Shit, nigga -- I'm locked, cocked and ready to rock!"
