Claims4
A thumb safety mechanism comprising:
- a first main body comprising an inner side surface;
- a pivot member comprising a first end coupled with the inner side surface of the first main body by a fastener, wherein the first main body is configured to pivot about the pivot member from a fire position to a safe position;
- a second main body coupled with a second end of the pivot member by a fastener;
- an engagement member protruding from the inner side surface of the first main body, wherein the engagement member is configured to block operation of a hammer when the first main body is in the safe position;
- and
- a removable cylinder, wherein the removable cylinder comprises an opening configured to accommodate the pivot member;
- wherein the pivot member is a monolithic piece of material that extends from the inner side surface of the first main body to the second main body;
- wherein the pivot member comprises an aperture configured to accommodate the fastener.
