Precision Materials & Finish
Material: 416R stainless steel — selected for excellent toughness, corrosion resistance, and fatigue life under repeated cycling.
Finish: QPQ (Quench-Polish-Quench) black — low friction, highly wear-resistant, and corrosion-fighting surface treatment favored in duty-grade components.
This combination yields a slide that looks refined, resists wear from holstering and carry, and stands up to rigorous use.
Optics-Ready Docter Cut
Pre-machined for a Docter-style footprint, the RA10P302A lets you mount popular micro red-dot optics quickly and securely. The cut is precision-located to Rival Arms’ tolerances and is compatible with common Docter-style mounting plates and adapters — dramatically improving target acquisition speed and sight picture in close to mid-range engagements.
Performance-Focused Design
Aggressive Front & Rear Serrations: Deep, well-spaced serrations provide positive purchase for press checks, slide manipulations, and one-handed operation — even with gloves or wet hands.
Optimized Ejection Port & Extractor Interface: Refined geometry promotes consistent case ejection and reduces stovepipe risks when paired with a quality recoil system and properly timed components.
Weight & Mass Tuning: Thoughtful milling and lightening cuts (where applicable) balance reciprocating mass for a crisp cycling feel while maintaining structural integrity.
Sight Compatibility: Works with factory and many aftermarket iron sight configurations (verify co-witness and compatibility after optic installation).
Fit & Compatibility
Designed to Fit: SIG P320 Carry configurations — confirm generation and specific carry frame before purchase.
Barrel & Recoil Compatibility: Accepts standard P320 barrels and recoil assemblies; when swapping slides, pair with recommended recoil spring and guide assembly to ensure reliable cycling.
Optic Mounting: Docter-style footprint — verify adapter/plate compatibility for the chosen red dot.
Installation Notes & Armorer Guidance
Drop-in installation: Compatible with standard P320 disassembly procedure. Basic armorer tools and knowledge recommended.
Optic Mounting: Use the correct mounting plate and torque fasteners to the optic manufacturer’s specs. Check the optic’s clearance and co-witness with iron sights if used.
Function Check: After installation, perform a full function and safety check and confirm reliable feeding, ejection, and slide lock with a variety of ammunition. If you encounter timing or fit issues, consult a qualified gunsmith or Rival Arms tech support.
Ideal Use Cases
Concealed-carry or duty carries that benefit from red-dot speed and improved sight picture.
Competition shooters converting a P320 Carry to an optics platform.
Enthusiasts who want a durable, high-quality slide upgrade for tactical handling and refined aesthetics.
Gunsmiths and custom builders creating optics-ready P320 builds.
Care & Maintenance
Keep slide rails clean and lightly lubricated with firearm-safe lubricant for smooth cycling.
Inspect mounting screws and optic plate torque periodically; retighten to manufacturer torque specs as needed.
Wipe the QPQ finish with a soft cloth after use; the QPQ surface resists corrosion but benefits from routine maintenance to extend longevity.
Safety & Legal Reminder
Modifying slides, adding optics, or otherwise altering a firearm can change its function and legal classification in some jurisdictions. Always follow local, state, and federal laws regarding firearms and modifications. Practice safe handling: clear the firearm before installation, follow all factory and armorer instructions, and consult a qualified gunsmith if you are not experienced with firearm assembly or optics mounting.
