A 6" Tactical pistol in 10mm, STI International's patented 2011 technology gives the STI "Perfect 10" more fire power advantage than 1911 tactical pistols. Combining this advantage with less felt recoil and other popular 2011 features, the STI "Perfect 10" is a superior pistol for all tactical applications. Built on the patented modular steel frame with polymer grip (the essential patented design element for high capacity) the STI "Perfect 10" delivers the added benefit of high capacity magazines without over-sizing the circumference of the grip. The STI "Perfect 10" 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. The STI "Perfect 10" has front and rear cocking serrations, STI dovetail front sight, and STI adjustable rear sight. The STI "Perfect 10" comes standard with features such as an STI stainless steel fully supported, ramped bull barrel, an STI two piece guide rod system, an STI aluminum magwell, an STI hi-ride grip safety, and STI ambi thumb safeties.
