STI Duty One Airgun 4.5mm 16732
STI DUTY ONE Airgun 4.5 mm | 1911-Inspired Power and Precision
Step into a new realm of shooting realism with the STI® DUTY ONE Airgun. From its authentic 1911-inspired lines to its heart-pounding blowback action, this semi-auto CO₂ pistol delivers everything an airgun enthusiast craves—every single time you pull the trigger. Licensed by Texas-based STI® International, the DUTY ONE’s rugged metal slide and ergonomic polymer frame bear genuine STI® markings and a unique serial number, marrying collectible pedigree with dynamic performance.
At the core of the DUTY ONE experience is its true-to-life recoil simulation. Each shot dispatches a 4.5 mm (.177) steel BB at up to 397 fps (121 m/s), and as the slide cycles, you’ll feel the same pulse and cadence of a full-size 1911 pistol. This immersive feedback keeps you engaged, refines your trigger control, and transforms routine range sessions into adrenaline-charged training drills.
Handling is second to none. The high-rise beaver-tail grip, embossed with the STI® logo, fills your palm and tames muzzle flip for rock-steady follow-up shots. When it’s time to reload, the drop-out magazine—loaded with 20 rounds—ejects in an instant, letting you swap in a fresh mag without missing a beat. Power comes courtesy of a single 12 g CO₂ cartridge housed snugly in the grip via our tool-free Easy-Load system. No fumbling, no extra tools—just pure, uninterrupted shooting fun.
Customization is built in. Mount a tactical light or laser on the integrated Weaver rail to lock down your sight picture, or thread on any standard silencer for stealthy operation. Whether you’re running drills in low light, fine-tuning your marksmanship, or simply blowing off steam at the range, the DUTY ONE adapts to your style.
Weighing in at 825 g (1.8 lb) with an overall length of 220 mm (8.8 in), this pistol balances solidity and portability. The robust construction stands up to relentless blowback cycling shot after shot, promising years of dependable service. From its sleek STI® styling to its match-grade performance, the DUTY ONE Airgun embodies precision engineering and sheer shooting pleasure—all wrapped into one dynamic package.
