This TRI-11 uses a government-length slide over a 5 inch barrel, paired with a steel frame and a 2011-pattern polymer double-stack grip module. It is sized as a full-size pistol and built on a 1911-style, single-action-only operating system.
The square-profile TRIARC compensator features visible porting, the TRIARC cross logo, and a "P" stamp. The fixed 3-dot iron sights include a front post mounted on the compensator and a rear sight with two white dots.
The slide is optic-cut and fitted with a four-screw cover plate; this pistol comes with an RMR mount installed. Front and rear cocking serrations aid slide manipulation.
Controls include an ambidextrous thumb safety and a beavertail grip safety. The fire-control setup features a flat-faced, lightened trigger and a skeletonized hammer. The grip module has aggressive stippling and a flared magwell for confident handling and streamlined reloads.
Capacity is 17+1 rounds, and two 17-round steel double-stack magazines are included. The dust cover carries a full-length 1913/Picatinny accessory rail. This model is compatible with many STI/Staccato-pattern 2011 magazines and components.
