The Hellcat Pro OSP Threaded pairs a compact footprint with a 4.4 in threaded barrel cut 1/2x28, finished in Melonite for corrosion resistance and wear durability. A thread protector is included, and the installed M*CARBO compensator is fitted to the factory threads.
The OSP slide features Springfield’s Micro/RMSc direct-mount optic footprint and co-witness-height U-Dot irons: a tritium/luminescent front dot and Tactical Rack U-notch rear. The slide wears a Desert FDE Cerakote finish that matches the FDE polymer frame.
This striker-fired pistol uses a flat-faced trigger shoe from M*CARBO and retains the factory trigger safety. The frame includes Adaptive Grip Texture and a dustcover accessory rail with multiple slots. A dual captive recoil spring with full-length guide rod manages slide movement.
