STI International’s patented 2011 technology gives the STI Tactical more fire power advantage than 1911 tactical pistols. Combining this advantage with less felt recoil and other popular 2011 features, the STI Tactical is a superior pistol for all tactical applications.

Built on the patented modular steel frame with polymer grip, the essential design element for high capacity, the STI Tactical delivers the added benefit of high capacity magazines without over-sizing the circumference of the grip. The STI Tactical is well suited for multiple applications; ranging from police and SWAT teams requiring a firearm with a light rail and high capacity, to the individual demanding a high performance pistol with special features for personal protection. The tactical rail milled into the dust cover of the frame accepts all industry standard light mounts.


Available in 4.15” with a unique slide or in 5.0” with a tactical scallop slide, the STI 5.0 Tactical has front and rear cocking serrations, the 4.15” has rear serrations, STI dovetail front sight, and STI fixed rear sight. Fixed tritium night sights or the TAS sights are an available option. The STI Tactical comes standard with features such as an STI stainless steel fully supported, ramped bull barrel, an STI Recoil Master guide rod system, an STI hi-ride grip safety, and STI ambi-thumb safeties. Calibers are 45 ACP, 9mm, and 40 S&W.
