A lock for a perforating gun system comprising, a housing, a cylinder formed in the housing, a piston assembly disposed within the cylinder, and anchoring arms coupled with the piston assembly. Detonation of the shaped charges of an associated perforating gun produces a pressure surge which is communicated to a surface of the piston assembly. Appropriate movement of the piston assembly outwardly rotates the anchoring arms into anchoring engagement with an associated tubular. Thus the pressure from the detonation event will anchor a perforating system within its associated tubular.
