STI‘s USPSA Double Stack model is a double-stack, 1911 chambered in 9mm, .40 SW or .45 ACP. Built on a patented modular steel frame with polymer grip, the USPSA Double Stack delivers the traditional features of a 1911 and allows the added benefit of high capacity magazines.
The innovative frame design preserves the 17-degree angle of the grip in relation to the slide, original to the 1911. The essential design element for high capacity, the polymer grip, allows for double stack magazines without over-sizing the circumference of the grip, which remains comparatively the same as the circumference of a 1911.
This pistol couples STI’s patented receiver with all the most desirable accessories in a factory firearm. The controls are STI’s stainless steel ambidextrous thumb safeties and knuckle relief high-rise beavertail grip safety. The full length forged stainless steel barstock slide features STI’s unique saber tooth rear cocking serrations, custom USPSA engravings, and is Tri-topped to reduce weight and felt recoil. The barrel is a 5″ fully ramped, fully supported bull barrel. This firearm comes standard with an STI square hammer, Recoil Master, patented STI trigger system, STI S-7 sear, and titanium strut for smooth, reliable function.
The USPSA Double Stack has black inlayed engraving on the polished sides of the two toned blued/stainless steel slide, stainless steel magwell, and an STI adjustable rear sight. The USPSA Double Stack has a two toned blued/stainless finish.
