The Hellcat Pro OSP configuration provides an optics cut that accepts the Springfield Micro (Shield RMSc) footprint, allowing a direct fit for compatible micro red dots without plates. Front and rear slide serrations aid press-checks and manipulations while maintaining a clean profile.
The 3.7" hammer-forged barrel and Melonite-treated, billet-machined steel slide emphasize durability and corrosion resistance. A dual-captive recoil spring with a full-length guide rod manages the compact slide’s cycle smoothly.
Sights are the U-Dot arrangement: a tritium front with a luminescent ring and a tactical rack U-notch rear for fast alignment. The pistol remains ready out of the box while leaving room for a low-profile optic.
The black polymer frame features Adaptive Grip Texture for a secure hold and includes a one-slot accessory rail on the dustcover for a light or other compatible accessory. The striker-fired action uses a trigger safety.
Dimensions are compact yet carry a 15+1 capacity: overall length about 6.6", height about 4.8", and weight around 21 oz. Markings include "CROATIA" proof/import stamps, with the serial number applied to the barrel hood, slide, and frame.
