Handgun brace/stock adaptor

Abstract

The pistol/stock adaptor allow conventional AR-style rifle stocks and pistol braces to be attached to the grip of a conventional handgun. The adaptor is a single integral component having a grip saddle that affixes the adaptor to a handgun, a buffer tube receiver that connects the buffer to the adaptor, and an elongated neck or bridge integrally connecting the grip saddle and the buffer tube receiver. The adaptor allows a shooter to “shoulder” the handgun against the shooter's torso, while maintaining a conventional two handed grip on the handgun.

I claim: 
     
         1 . An adaptor for connecting an AR-style buffer tube to a pistol, where the pistol includes a pistol frame having a pistol grip and reciprocating slide, and where the buffer tube has a first tube end and a second tube end, the adaptor comprising:
 an elongated adaptor body having a first adaptor body end thereof and a second adaptor body end thereof,   the adaptor body has a grip saddle at the first adaptor body end configured to receive the pistol grip and securely affixed the adaptor to the pistol grip, so that the pistol slide reciprocates over the adaptor body,   the adaptor body has a buffer tube receiver at the second adaptor body end configured to receive the first tube end of the buffer tube and affix the buffer tube to the adaptor,   the adaptor body has a bridge part integrally extending axially between the grip saddle and the buffer tube receiver.   
     
     
         2 . The adaptor of  claim 1  wherein the grip saddle includes a grip cover that extends over the pistol grip and is contoured to allow the grip saddle to be grasped by a shooter. 
     
     
         3 . The adaptor of  claim 1  wherein the grip saddle also includes a pair of side members that extend over and around the sides of the pistol grip. 
     
     
         4 . The adaptor of  claim 3  wherein the adaptor body is secured to the pistol grip by a pin that extends laterally through the pistol grip between the pair of side members of the grip saddle. 
     
     
         5 . The adaptor of  claim 1  wherein the adaptor body is secured to the pistol grip by an adhesive applied between the grip saddle and the pistol grip. 
     
     
         6 . The adaptor of  claim 1  wherein the buffer tube receiver has a cylindrical bore for axially receiving the first buffer tube end so that the buffer tube extends longitudinally from the adaptor body at the second adaptor body end. 
     
     
         7 . The adaptor of  claim 6  wherein the adaptor body has a longitudinal axis thereof, when the adaptor is connected to the pistol, the longitudinal axis of the adaptor body is parallel to the pistol slide, the buffer tube extends from the adaptor body at an angle relative to the longitudinal axis of the adaptor body. 
     
     
         8 . The adaptor of  claim 1  wherein the buffer tube receiver includes a swivel socket. 
     
     
         9 . The adaptor of  claim 1  wherein the buffer tube receiver includes a rail interface for detachably connecting firearm accessories to the adaptor. 
     
     
         10 . The adaptor of  claim 9  wherein the buffer tube receiver includes a second rail interface for detachably connecting the firearm stock to the adaptor. 
     
     
         11 . An adaptor for connecting a rifle stock to a handgun, where the handgun has barrel and a handgun grip, and where the rifle stock includes an elongated buffer tube a first tube end and a second tube end and a stock part connecting the second tube end buffer tube, the adaptor comprising:
 an elongated adaptor body having a first adaptor body end thereof and a second adaptor body end thereof,   the adaptor body has a grip saddle at the first adaptor body end configured to receive the handgun grip and securely affix the adaptor to the handgun grip,   the adaptor body has a buffer tube receiver at the second adaptor body end configured to receive the first tube end of the buffer tube and affix the buffer tube to the adaptor,   the adaptor body has a bridge part integrally extending axially between the grip saddle and the buffer tube receiver.   
     
     
         12 . The adaptor of  claim 11  wherein the grip saddle includes a grip cover that extends over the handgun grip and is contoured to allow the grip saddle to be grasped by a shooter. 
     
     
         13 . The adaptor of  claim 11  wherein the grip saddle also includes a pair of side members that extend over and around the sides of the handgun grip. 
     
     
         14 . The adaptor of  claim 13  wherein the adaptor body is secured to the handgun grip by a pin that extends laterally through the handgun grip between the pair of side members of the grip saddle. 
     
     
         15 . The adaptor of  claim 11  wherein the adaptor body is secured to the handgun grip by an adhesive applied between the grip saddle and the handgun grip. 
     
     
         16 . The adaptor of  claim 11  wherein the buffer tube receiver has a cylindrical bore for axially receiving the first buffer tube end so that the buffer tube extends longitudinally from the adaptor body at the second adaptor body end. 
     
     
         17 . The adaptor of  claim 16  wherein the adaptor body has a longitudinal axis thereof, such that when the adaptor is connected to the handgun, the longitudinal axis of the adaptor body is parallel to the handgun barrel, the buffer tube extends from the adaptor body at an angle relative to the longitudinal axis of the adaptor body. 
     
     
         18 . The adaptor of  claim 11  wherein the buffer tube receiver includes a swivel socket. 
     
     
         19 . The adaptor of  claim 11  wherein the buffer tube receiver includes a rail interface for detachably connecting firearm accessories to the adaptor. 
     
     
         20 . The adaptor of  claim 19  wherein the buffer tube receiver includes a second rail interface for detachably connecting the firearm stock to the adaptor.
