Apex Slide for Hellcat and Hellcat Pro

This partially stripped slide assembly for the Hellcat and Hellcat Pro is machined from heat-treated stainless steel, providing a direct replacement for the factory slide with an integrated optic cut for Holosun K-series optics. The primary problem it solves is the lack of a factory direct-mount solution for micro red dots on these platforms, eliminating the need for adapter plates or milling services. It accepts all factory Hellcat slide internals and barrels, as well as Apex aftermarket components. Note: this is a partially stripped slide; you must transfer or procure all internal parts, barrel, and recoil assembly.

Compatibility

• Springfield Hellcat (all variants)
• Springfield Hellcat Pro (all variants)
• Fits Holosun 407K, 507K, EPS, and EPS Carry optics
• Fits Shield Arms RMSC optics (use screws included with optic)
• Works with all factory Hellcat slide components and barrels
• Works with all Apex aftermarket Hellcat slide components and barrels

Key Features

• Material & Finish: Machined from heat-treated stainless steel. Black slides receive a PVD finish; FDE slides have Cerakote applied to visible surfaces over the PVD base.
• Optic Mounting: Direct-mount cut for Holosun K-series (407K, 507K, EPS, EPS Carry) and Shield RMSC. Mounting screws for Holosun K-type optics included. Threads are 4mm x 0.7mm with 4+ engagement threads for maximum optic retention.
• Extractor Integrity: Optic mount holes do not penetrate the extractor spring channel, preventing screw interference with the extraction system.
• Manufacturing: 100% made in the USA (Phoenix, AZ).
• Note: This is a partially stripped slide. Requires installation of: striker assembly, striker block & spring, extractor & extractor plunger assembly, slide back plate, barrel, and recoil assembly.

Install Difficulty: 3 out of 5

Moderate. Requires armorer-level knowledge of Hellcat slide assembly. Tools needed: sight pusher or punch set for front/rear sights, roll pin punch set, small hammer, and a torque driver (15-18 in-lbs) for optic mounting screws. Transferring internal parts from the factory slide is straightforward but requires attention to spring orientation.

Frequently Asked Questions

Does this slide include the barrel and recoil spring?

No. This is a partially stripped slide. You must transfer or purchase separately: barrel, recoil assembly, striker assembly, striker block & spring, extractor & plunger assembly, and slide back plate.

Will this fit my Hellcat Pro without modification?

Yes. This slide is machined to fit both the standard Hellcat and Hellcat Pro frames. All factory internals and Apex aftermarket components are compatible.

Can I use an adapter plate with this slide for other optics?

No. The optic cut is specific to the Holosun K-series footprint and Shield RMSC. Adapter plates will not fit the recessed cut profile. For other footprints, you will need a different slide or a plate-milled option.

Shipping & Warranty: Ships within 1-3 business days from Phoenix, AZ. This slide carries a limited lifetime warranty against manufacturing defects.
