The XDm Threaded Barrel configuration delivers a factory-threaded, match-grade barrel with 0.578x28 threads and a Melonite-treated finish, paired with a protective thread cap. The extended barrel and one-piece full-length guide rod support consistent performance with .45 ACP.
Its forged steel slide wears a durable black Melonite finish and integrates a loaded chamber indicator. Suppressor-height steel 3-dot sights provide a clear sight picture over the threaded muzzle and complement the slide’s robust construction.
Ergonomics and controls are a focal point: an ambidextrous magazine release, interchangeable FDE backstraps, and the 3-slot Picatinny-style accessory rail on the dust cover make the platform adaptable to different users and setups.
Safety and status features include a grip safety, trigger safety, a loaded chamber indicator, and a striker status indicator. The striker-fired action, full-size frame, and 13+1 capacity with the included magazines round out a well-equipped .45 ACP package manufactured by HS Produkt in Croatia and imported/marketed by Springfield Armory.
