half-cock

Hammer's safety position

Half-cock is the position of a gun's hammer when partially drawn back, locked but not ready to fire—a safety position that prevents accidental discharge.

The phrase go off half-cocked or go off at half-cock means to act prematurely or without proper preparation, like a gun firing before it's fully ready.
