ABSTRACT:
A safety system for firearms is provided for a firearm of the type in which a hammer is urged into a cocked position and then actuated by a trigger. The safety system includes a thumb safety which is movably mounted on the hammer. The thumb safety and the hammer comprise a hammer assembly, which has a firing configuration in which it is configured to strike the firing pin. When the hammer assembly is in its safe configuration, the thumb safety precludes the hammer from actuating.
