Abstract
The present invention is a handgun having a polymeric frame with metallic rails that are inserted within the frame after the frame has been formed by a molding process. The rails are inserted into recesses formed in a channel within the frame, before the frame has completely cooled and contracted. The rails comprise a pair of front rails and a pair of rear rails. The rear pair of rails are positioned within rear recesses and held in place by the sear block. The front pair of rails are positioned within front recesses and held in place by a plurality of metallic parts. The parts include a horseshoe, an unlock block, and a spreader block that are positioned between and matingly engage the front rails, thus securing them within their respective recesses.
