STI’s Dynamic Duo | STI 1911 Pistol Review

TACTICAL 4.15 .45ACP
STI International’s patented 2011 technology gives the Tactical 4.15 more firepower advantage than 1911 tactical pistols. Combining this advantage with less felt recoil and other popular 2011 features, the Tactical 4.15 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 Tactical 4.15 delivers the added benefit of high capacity magazines without over-sizing the circumference of the grip. It is well suited for multiple applications, ranging from 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 Tactical 4.15 with its unique slide, it features rear serrations, STI dovetail front and fixed rear sight. Fixed tritium night sights are an available option. It comes standard with such features as an STI stainless steel fully supported, ramped bull barrel, an STI RecoilMaster guide rod system, an STI aluminum magazine well, an STI knuckle relief hi-ride grip safety, and STI ambidextrous thumb safeties.
