Pistol frame

Abstract

Pistol frames have a pair of opposed frame shells, the frame shells separable contacting each other at a medial plane, the shells defining a plurality of registered apertures configured to receive a plurality of registration elements, and the shells collectively defining a rail receptacle configured to receive a rail module. The shells may be formed of metal and be an integral unitary element. The shells may define a plurality of receptacles each configured to receive a rail module. The shells may at least in part define a magazine well having opposed sidewalls. The rail receptacle may be in open communication with the magazine well. The magazine well may have opposed side surfaces and opposed front and rear surfaces, the rear surface extending from a lower grip end of the frame and having an upper terminus at an intermediate location spaced apart from an upper limit of the frame.

I claim: 
     
         1 . A pistol frame comprising:
 a frame body having a rail connection facility configured to connect to a rail module;   the frame body at least in part defining a magazine well having opposed sidewalls; and   a rail module connected to the rail connection facility, the rear rail module in part defining the magazine well.
