Abstract

An elongated firing pin is constructed of titanium and defines a plurality of voids therein such that the firing pin is lightweight. The elongated firing pin extends axially and includes a tip at the pin front and a radially extending protrusion at the pin rear. The radially extending protrusion defines a first cavity that is accessible at the pin rear. The firing pin further includes an axially extending external surface and an axially extending internal surface. The internal surface surrounds and defines an elongated, axially extending bore that is accessible at the pin rear. The firing pin further defines a second cavity, and the second cavity is accessible at the external surface proximate to firing pin front. The firing pin additionally defines a third cavity that is also accessible at the exterior surface proximate to the pin front.
