Patent ID: 8276302

Claim:
A firearm having a manual safety and a hammer-type firing mechanism, the firearm comprising: a frame having a frame protrusion formed on the side of the frame and rearward on the frame, wherein the frame protrusion has a substantially quadrilateral shape, and defining a frame recess in a side of the frame adjacent to a lower end of a hammer-type firing mechanism, wherein the frame recess is defined in part by a frontward wall of the frame; a hammer of a hammer-type firing mechanism rotatably mounted to the frame, wherein the hammer defines a hammer recess abutting the frame recess; a slide having a lower edge reciprocally mounted to the frame, wherein the lower edge defines a triangular slide recess; a tab pivot located substantially below the frame protrusion on the side of the frame; a tab rotatably mounted to the tab pivot, wherein the tab is releasably engageable with the slide recess, wherein the tab has a tab extension that protrudes laterally from the tab, wherein the tab extension is releasably engageable with the hammer recess, a triangular protrusion that extends from a frontward edge of the tab and a grooved portion for promoting traction and facilitating manipulation by a user; and a detent spring mounted to the frame and releasably engageable with the triangular protrusion, wherein the detent spring biases the tab into and out of engagement with the slide recess and the tab extension into and out of engagement with the hammer recess; wherein the tab abuts the frame protrusion when actuated into engagement with the slide recess and the tab extension abuts the frontward wall of the frame recess when actuated into engagement with the hammer recess; wherein the tab is configured such that at a point along a movement arc of the tab, the tab extension engages with the hammer recess and the tab engages with the slide recess; and whereby actuation of the tab into engagement with the slide recess and the tab extension into engagement with the hammer recess blocks the slide from reciprocating on the frame and the hammer from rotating in the frame, respectively, which disables the firearm.
