Compact semiautomatic firearm

Abstract

A semi-automatic firearm apparatus has a recoil rod having a recoil spring associated with it, wherein the recoil rod faces in a first direction and projects outwardly from the semi-automatic firearm apparatus and a hold back member connected to the semi-automatic firearm apparatus and movable between a first position where it does not block the movement of the recoil rod and a second position where it does block the movement of the recoil rod.

What is claimed is: 
     
         1 . A semi-automatic firearm apparatus, comprising:
 a recoil rod having a recoil spring associated with it, wherein the recoil rod faces in a first direction and projects outwardly from the semi-automatic firearm apparatus; and   a hold back member connected to the semi-automatic firearm apparatus and movable between a first position where it does not block the movement of the recoil rod and a second position where it does block the movement of the recoil rod.   
     
     
         2 . A semi-automatic firearm apparatus according to  claim 1  wherein the hold back member is connected to the semi-automatic firearm apparatus so that it is rotatable from the first position to the second position. 
     
     
         3 . A semi-automatic firearm apparatus according to  claim 1  wherein in the second position the hold back member holds a bolt of the semi-automatic firearm apparatus in an open position. 
     
     
         4 . A semi-automatic firearm apparatus, comprising:
 a side frame with an internal surface; and   at least one recess in the internal surface.   
     
     
         5 . A semi-automatic firearm apparatus according to  claim 4  wherein the at least one recess is molded into the internal surface. 
     
     
         6 . A semi-automatic firearm apparatus according to  claim 4  wherein there are a plurality of recesses in the internal surface. 
     
     
         7 . A safety mechanism of a semi-automatic firearm, comprising:
 a trigger;   a striker; and   a safety block located immediately above the trigger, wherein the safety block is configured to travel downwards as the trigger travels rearwards and to engage a portion of the striker so as to prevent its further forward movement.   
     
     
         8 . A safety mechanism of a semi-automatic firearm according to  claim 7  wherein the safety block has a recess shaped to receive a nose of the striker.
