Abstract
A combination metal/polymer frame is used with a pistol where the frame comprises a polymeric frame housing defining a barrel receiving portion and a stock portion. A metal stock insert is secured within the polymeric frame housing and is configured to mount a pistol fire control group on the frame. Additionally or alternatively, a metal frame insert is configured to removably reside within the polymeric frame housing. The metal frame insert defines an opening through which a round is communicated from a pistol magazine to a pistol chamber.
