Fire control group

Abstract

A fire control group has a receiver having opposed sidewalls defining a space configured to receive a fire control group, the opposed sidewalls each defining a pivot pin aperture, the pivot pin apertures being registered with each other, a fire control group including a trigger received in the space, the fire control group defining a transverse pivot pin passage configured to be registered with the pivot pin apertures of the receiver, the fire control group including a pivoting operational element, the fire control group including a pivot pin supporting the pivoting operational element and received in the transverse pivot pin passage and the pivot pin apertures, the firearm having a hand grip aft of the trigger and defining a screw aperture, and a grip screw engaging the hand grip and engaging the fire control group. The grip screw may occupy a medial plane of the firearm.

I claim: 
     
         1 . A firearm comprising:
 a receiver having opposed sidewalls defining a space configured to receive a fire control group;   the opposed sidewalls each defining a pivot pin aperture;   the pivot pin apertures being registered with each other;   a fire control group including a trigger received in the space;   the fire control group defining a transverse pivot pin passage configured to be registered with the pivot pin apertures of the receiver;   the fire control group including a pivoting operational element;   the fire control group including a pivot pin supporting the pivoting operational element and received in the pivot pin passage and the pivot pin apertures;   the firearm having a hand grip aft of the trigger and defining a screw aperture;   a grip screw engaging the hand grip and engaging the fire control group; and   wherein the fire control group defines an aperture receiving the grip screw.
