A convertible sidearm is provided which can convert easily between a firearm and a knife. The convertible sidearm includes a tubular body frame. A back plate member assembly is removably affixed to the tubular body at one end. The back plate assembly includes a plate member and a substantially tubular support member emanating outwardly from a planar surface of the plate member. A standard bolt or bolt carrier assembly from a primary firearm, having a bolt and a firing pin connected thereto, is inserted into the tubular support member of the back plate member assembly. A spring-loaded striker is positioned proximal to a firing pin within the bolt carrier assembly. A trigger communicates with the spring-loaded striker to release the striker toward the firing pin to fire the weapon. The firearm is easily converted to a knife by removing the barrel of the firearm and replacing it with a blade assembly and removing the bolt carrier assembly from the back plate member assembly and re-installing the back plate member within the tubular body member. Alternatively, the convertible sidearm may employ a permanent firing mechanism instead of a removable bolt or bolt carrier.
