STI International has fully licensed this pistol with the 1911 in mind, only with upgraded functions and design. The air pistol has blowback semi-automatic action powered by 12gram Co2, which is stored in the pistol grip. The high rise beaver-tail grip provides a tight hold to help you feel secure while you are shooting. The STI Duty One is marked with the STI logo on the full metal slide and a serial number, so you know your pistol is unique.
