The Comp OSP variant integrates a compensator system with a dedicated slide port and barrel design, delivering the comp feature in a streamlined factory package. The 3.7 in hammer-forged barrel wears a Melonite finish, and the slide is Melonite finished as well with Springfield Armory’s crossed-cannon crest.
The slide is OSP-cut and supplied with a cover plate, and it uses the Shield RMSc/Springfield Micro footprint for direct-mount micro optics. Front and rear cocking serrations aid manipulation, while the factory U-Dot sight system combines a tritium front with a high-visibility ring and a steel U-notch rear.
The black polymer frame features a two-slot accessory rail on the dustcover, a flat-faced trigger with an integral trigger safety, and a left-side magazine release. There is no external thumb safety.
Capacity is 17+1 with the included 17-round magazine, and the pistol also comes with a 15-round magazine. The stainless steel magazines are provided with both flush and extended baseplates as supplied for the Hellcat Pro.
Markings include “HS PRODUKT MADE IN CROATIA,” reflecting its Croatian manufacture for Springfield Armory. The serial markings on the barrel hood and frame correspond with the box label and factory test target for this specific pistol.
