The original polymer grip was formerly a shared patent design between Strayer-Voigt and STI International Inc. It offers a modular version of the M1911 design optimized for competition use. By making the lower half of the frame from thin polymer, the gun can make use of double-stack magazines without a significant increase in grip thickness (current production utilizes various metals for the grip).
