The present invention is a handgun (10) having a polymeric frame (30) with metallic rails (70) 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 (40) within the frame, before the frame has completely cooled and contracted. The rails comprise a pair of front rails (72, 74) and a pair of rear rails (76, 78). The rear pair of rails is positioned within rear recesses and held in place by the sear block (18). The front pair of rails is positioned within front recesses (52, 54) and held in place by a plurality of metallic parts. The parts includes a horseshoe (120), an unlock block (130), and a spreader block (140) that are positioned between and matingly engage the front rails, thus securing them within their respective recesses.

Arme de poing (10) ayant une structure polymère (30) munie de rails métalliques (70) insérés à l'intérieur de la structure après mise en forme de la structure par un procédé de moulage. Les rails sont insérés dans des cavités formées dans une gorge (40) ménagée dans la structure avant que la structure ait complètement refroidi et se soit contractée. Les rails comprennent une paire de rails avant (72, 74) et une paire de rails arrière (76, 78). La paire de rails arrière se situe dans des cavités arrière et est maintenue en place par le bloc gâchette (18). La paire de rails avant se situe à l'intérieur de cavités avant (52, 54) et est maintenue en place par une pluralité de pièces métalliques. Ces pièces comprennent un fer à cheval (120), un bloc de déverrouillage (130), et un bloc d'écartement (140) placés entre les rails avant et s'appuyant sur ceux-ci, les fixant dans leurs cavités respectives.
