The Springfield Armory Hellcat Pro Comp OSP is an integrally compensated, striker-fired semi-automatic handgun meticulously designed for concealed carry and home defense. Chambered in 9mm Luger, it incorporates a single top-ported expansion chamber machined directly into the 3.7-inch hammer-forged steel barrel and slide to redirect gases upward, effectively flattening muzzle flip for rapid follow-up shots. This optics-ready pistol natively accepts micro red dots sharing the Springfield Micro / Shield RMSc footprint while maintaining a slim 1-inch grip profile, premium tritium night sights, and a versatile 15+1 and 17+1 round capacity.
