locked and loaded and good to go
Prepared for an imminent activity. Believed to have originated during WWII, referring to the M1 Garand rifle, whose bolt automatically "locked" a round in the chamber when the rifle was "loaded" with a magazine, which could then be immediately fired without any further preparation required.
