STI International has a hard-earned reputation for providing shooters with cutting-edge pistols. It is best known for its 2011-series pistols, which are some of the most popular high-capacity, 1911-style pistols on the market. So popular are they, in fact, that it is easy to forget that STI also builds some excellent single-stack 1911 pistols. With handguns ranging from the bare bones models to competition pistols designed specifically for the action-pistol game, STI covers the gamut. For example, STI ‘s 1911 line is one of the most complete for concealed carry. The Shadow remains a favorite for use as a backup or a deep-concealment gun for officers and agents. The Escort is one of the lightest 3-inch .45 ACP pistols on the market. All of STI’s pistols feature high-quality parts, and they are among the most reasonably priced on the market.
One of the company’s most popular 1911 pistols is the Duty One. Its straightforward and rugged design fits its name, and it works well for any mission it’s given. For 2013, STI has added 3-inch and 4-inch variants as companions to the standard 5-inch Duty One. Aside from expanding the line, the company also listened to customers and made a few upgrades. The process has resulted in one of the best options on the market for a concealed-carry or duty 1911.
All Duty One 1911s are available in 9mm, .40 S&W and .45 ACP, and each starts with a forged-steel, standard-width frame that utilizes STI’s new Picatinny rail system. The rail allows you to add lights and lasers without making the pistol too bulky or heavy. An innovative “grid” serration pattern adorns the rear of each frame with matching frontstrap serrations. The front cocking serrations are abbreviated, giving each Duty One a very clean look. New G10 grip panels, along with a flat-checkered mainspring housing, provide for a very solid grip.
