The Steyr Arms ATC Base is a full stainless-steel 9mm competition pistol developed as the entry model in Steyr’s ATC sport-shooting lineup. It features a 5" cold hammer-forged chromoly steel barrel, stainless steel frame & slide, brushed stainless finish, optics-ready slide, front & rear slide serrations, adjustable LPA-style sights, ambidextrous magazine release, interchangeable grip panels, Picatinny accessory rail & a hammer-fired SA/DA trigger system. Designed for professional sport-shooting entry, precision range use & competition training, the ATC Base gives shooters a stable steel-frame platform with modular ergonomics, excellent balance and strong accuracy potential. Steyr Arms has a long reputation for precision Austrian firearms engineering & the ATC Base reflects that approach with hand-fitted custom-grade components, a cold hammer-forged barrel & a full stainless-steel construction intended for durability & repeatable performance. The factory-tuned SA/DA trigger is designed to provide a smooth double-action pull with a crisp single-action break & short reset, while the 33.5 oz. weight with empty magazine helps reduce muzzle movement during rapid fire. Its optics-ready slide, adjustable sights, 18 rd standard capacity, optional 20 rd magazines & modular grip panels make it a capable foundation for shooters entering practical pistol competition or refining high-volume range skills.
