The Springfield Armory Hellcat Pro Comp OSP CA Compliant is an integrally compensated, striker-fired semi-automatic handgun precisely configured for California restrictive compliance and added to the CA DOJ Handgun Roster. Chambered in 9mm Luger, this model utilizes a single top-ported expansion chamber cut directly into the 3.7-inch hammer-forged steel barrel and slide to redirect gases upward, flattening muzzle flip for rapid follow-up tracking. Meeting all California requirements, it incorporates a magazine disconnect safety and a physical top-mounted loaded chamber indicator (LCI). The optics-ready OSP slide natively interfaces with Shield RMSc footprint micro red dots and co-witnesses with premium tritium U-Dot night sights while delivering a state-compliant 10+1 capacity.
