Not long after STI International released the 6-inch barrel double-stack 2011 Perfect 10 pistol chambered in 10 mm, customers requested a single-stack version with a 5-inch barrel. This year, STI fans will get their wish with the new Nitro 10 pistol. Built using STI's 1911 Government forged steel frame, this 10mm has a classic, round-top slide with wide front and rear slide serrations. The 5.01-inch bull barrel is ramped for improved feeding and has a fully supported chamber. Available in a blued finish with the flats of the slide polished, this 10 mm will come in handy for target practice at the range, tactical shooting, or hunting big game.
