The Springfield Armory Hellcat Pro is built on a Flat Dark Earth Cerakote-finished steel slide and a Flat Dark Earth polymer frame, with the Cerakote surface treatment applied at the factory to provide a uniform, corrosion-resistant finish that withstands daily carry exposure to sweat, salt, moisture, and environmental contamination over the long term. The factory-milled optic-ready slide is machined to accept miniature red dot sights directly, and the Viridian RFX11 green dot included in this Gear Pac mounts directly to the slide for an immediate, zero-battery-delay green dot aiming solution tuned for both indoor and outdoor lighting conditions.
