The Springfield Armory Hellcat Pro OSP and Hellcat OSP are both 9mm pistols that are optics ready:
Hellcat Pro OSP
This pistol has a 3.7 in hammer forged steel barrel with a Melonite finish and a black polymer frame with an adaptive grip texture. It comes with two magazines, a 15-round flush-fitting mag and a 17-round extended mag. The Hellcat Pro OSP also has tritium/luminescent front sights and a tactical rack U-notch rear sight.
Hellcat OSP
This pistol was originally available as an optic-ready configuration for an extra charge, and OSP stands for "Optical Sight Pistol".
The Hellcat Pro has a frame, slide, and barrel that are about half an inch longer than the standard Hellcat, which gives it more space on the accessory rail for mounting a laser or light. All Hellcat Pro models also come with a slide cut for mounting a red dot sight that fits the Shield RMSc footprint.
