Extendable tang for a firearm

An extendable grip tang for a firearm, the extendable grip tang comprising:

• a. a tang body concealable, in a stowed orientation, within a cavity in a firearm grip;
• b. a plunger connected to the tang body, the plunger further comprising an upper section and a lower section with a vertical slot disposed in the upper portion of the plunger;
• c. a spring in operable communication with the plunger;
• d. a pivoted, forked lock bar having two tines spaced apart, an outer tine accessible from the outside the firearm grip;
• wherein, the inner tine supports the plunger by interfacing with a top of the vertical slot, thereby compressing the spring, and, when the outer fork of the lock bar is pushed inward into the grip, the inner tine and plunger disengage, allowing the plunger free movement between the tines of the lock bar and decompression of the spring, forcing deployment of the tang.
