Since its introduction in late 1997, the STI Edge has become the undisputed standard for USPSA/IPSC Limited Division competition shooting as demonstrated by Michael Voigt and Frank Garcia finishing one/two as they led the US IPSC Limited Team to victory at World Shoot XII. It has been adopted by SWAT teams, HRT teams, street cops, and law enforcement training sites. It has been embraced by almost all other shooting disciplines.

Built on the STI Modular Steel 2011® frame with polymer grip, the Edge delivers the traditional features of a 1911 and allows the added benefit of high capacity magazines. The innovative frame design preserves the 17° 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.

True to 1911 tradition, the Edge has a unique full length slide with front and rear cocking serrations, STI dovetail front sight and STI adjustable rear sight. The Edge comes standard with features such as a stainless steel STI knuckle relief hi-ride grip safety and stainless steel STI ambi-thumb safeties. It comes with an STI stainless steel fully supported, ramped bull barrel. Not only is it the most accurate and reliable handgun on the market, it is also one of the most beautiful.
