Abstract

A safety mechanism for a firearm includes a hammer block engageable with the hammer to prevent the hammer from moving into engagement with the firing pin. The hammer block is manually shifted between its active and inactive positions through a safety cam having a positive driving connection with the block. As the cam is moved to shift the block from its non-blocking to its blocking position, the cam also engages the sear to release the sear from the trigger and to allow the hammer to move from its cocked position into a safety position in engagement with the hammer block. A compact arrangement is obtained by having the safety cam non-rotatably carried by an operating shaft which also serves as the pivot pin for the hammer and by having the hammer spring received in a hammer recess in surrounding relation to the safety cam operating shaft. The hammer block and sear are also mounted on a single pivot pin common to the two parts.
