Interchangeable grip for a firearm

Abstract

Methods, systems, and apparatuses for interchangeable, customizable, and suitable grips for firearms are described. In some embodiments, the grip includes two components, a grip base piece and an interchangeable grip (e.g., an interchangeable grip attachment) of the firearm user's choice. The grip base piece attaches to the lower receiver held by a pistol grip screw and a lock washer. In some examples, the grip base piece may only be installed once, for example, initially prior to implementation of interchangeable grips (e.g., the grip base piece may not require any other attention or installation changes after the initial placement onto the lower receiver). Following the installation of the grip base piece on the lower receiver, interchangeable grips of users' choice may be connected to the grip base piece (e.g., and interchanged with other interchangeable grips) via utilizing a grip interface (e.g., a T-shaped mating tab of the interchangeable grip).

What is claimed is: 
     
         1 . A trigger lock system for a firearm comprising:
 a grip base piece comprising:
 a receiver interface configured to couple to a firearm receiver, wherein the receiver interface comprises a base shape configured to couple to a corresponding receiver shape at a firearm grip mounting location, wherein the corresponding receiver shape at the firearm grip mounting location is part of the firearm receiver; and 
 a grip base interface comprising a recess; and 
   a trigger lock comprising:
 a trigger lock interface configured to couple to the grip base interface, wherein the trigger lock interface comprises a grip interface shape configured to couple to a corresponding grip base piece shape at a grip mounting location, wherein the grip interface shape at the grip mounting location is part of the trigger lock interface of the grip base piece, wherein the trigger lock is selectively slidable at the trigger lock interface relative to the grip base interface to release the trigger lock from the grip base piece; 
 a trigger lock body comprising a pin-guide; 
 a pin disposed within the pin-guide, wherein the pin protrudes into the recess of the grip base interface temporarily preventing sliding of the trigger lock interface relative to the grip base interface; and 
 a pair of cover plates extending above the trigger lock body and forward over a trigger space, wherein one of the pair is positioned on a left side of the trigger space, and another of the pair is positioned on a right side of the trigger space, wherein access to the trigger space is limited by the pair of cover plates. 
   
     
     
         2 . The trigger lock system of  claim 1  comprising:
 a spring interposed between the trigger lock body and the pin, wherein the spring holds the pin in a first position protruding into the recess, and wherein when the spring is deflected allows the pin into a second position, removing the pin from the recess, and permitting selective sliding of the trigger lock from the grip base piece. 
 
     
     
         3 . The trigger lock system of  claim 1  comprising:
 a lock mechanism between the trigger lock body and the pin, wherein the lock mechanism holds the pin in a first position protruding into the recess, and wherein when the lock mechanism is unlocked the pin is moved into a second position, removing the pin from the recess, and permitting selective sliding of the trigger lock from the grip base piece. 
 
     
     
         4 . The trigger lock system of  claim 1  comprising:
 said trigger lock interface, wherein said trigger lock interface comprises a T-shaped cross section; and 
 said grip base interface, wherein said grip base interface comprises a T-shaped cross section. 
 
     
     
         5 . The trigger lock system of  claim 4  comprising:
 said trigger lock interface, wherein said trigger lock interface comprises said T-shaped cross section of a T-shaped rail extending away from said trigger lock body; and 
 said grip base interface, wherein said grip base interface comprises said T-shaped cross section of a T-shaped channel in said grip base piece. 
 
     
     
         6 . The trigger lock system of  claim 1  comprising:
 said grip base piece comprising:
 a mounting hole adapted to receive a fastener that couples the grip base piece to said firearm receiver. 
 
 
     
     
         7 . The trigger lock system of  claim 6  comprising:
 said fastener. 
 
     
     
         8 . The trigger lock system of  claim 7  comprising:
 said fastener, wherein said fastener comprises a bolt. 
 
     
     
         9 . The trigger lock system of  claim 8  comprising:
 a lock washer encircling said bolt, wherein said lock washer is interposed between said bolt and said grip base piece.
