ASG Licensed STI International Duty One 1911 Blowback CO2 Pistol

The NEW Duty One 1911 CO2 Pistol is ASG's accurate take on one of STI International's most popular pistol models, which have gone through an extensive evolution and morphed these classic pistols into modern sidearms. From the hammer all the way to the rail system, this pistol is built to look and feel like an STI pistol. As with the real steel version, reliability ranks high on its list as well as aesthetics.

Modeled off a government size frame, this licensed Duty One series pistol measures 9 inches long and features STI's innovative Picatinny rail system, which can accept most industry flashlights and laser units. This blowback pistol is built using standard 1911 specs but also includes a commander style hammer, separating this model from most older M1911 pistols on the market. Coupled with its checkered pistol grip and high-rise beavertail safety grip, which prevents slide bite, the Duty One replica provides excellent hold and is a fine choice that keeps ergonomics in mind — and shooting well into 400-FPS territory helps as well. This designates it as an exceptional pistol for law enforcement training scenarios as it will also fit into standard M1911 holsters and comes integrated with fixed iron sights.

The Duty One CO2 pistol by ASG is engraved with STI International's official trademarks and unique serial number etched onto the full metal slide, adding a final touch of authenticity. The frame is constructed out of nylon polymer, which not only helps reduce weight but makes it extremely durable. Single sided thumb safety and an easy-open CO2 compartment only adds onto the list of what qualifies this licensed model to be a must-have. Anyone looking into picking up a reliable blowback pistol with real steel licensing and hard-hitting specs will find the STI Duty One 1911 CO2 pistol to be perfect.
