Rival Arms Slide Completion Kit — Sig P365 — Black PVD Stainless Steel (Model RA42P002A, UPC: 788130031377)
Give your Sig Sauer P365 slide a precision refresh or professional upgrade with the Rival Arms Slide Completion Kit (RA42P002A). Built from corrosion-resistant stainless steel components and finished in durable Black PVD, this slide completion kit delivers the wear parts and upgraded internals you need to restore reliable striker ignition, rock-solid extraction, and consistent function — all while providing a matched low-glare appearance. Ideal for armorers, custom builders, and P365 owners who demand longevity and performance from their carry pistol.
Why the Rival Arms RA42P002A Matters
The slide on a striker-fired pistol is exposed to carbon, impacts, and wear. Worn springs, extractors, or striker components can cause light strikes, failures to extract, or inconsistent firing. The RA42P002A addresses those failure points with precision-made replacements designed specifically for the Sig P365, restoring factory-spec function or elevating durability on high-round-count pistols.

Key Features & Benefits
Platform-Specific Fit: Engineered for Sig Sauer P365 slides — reduces fitting time and minimizes surprises during installation.
Stainless Construction: Corrosion-resistant parts for increased longevity compared to coated mild-steel replacements.
Black PVD Finish: Low-glare, wear-resistant finish on visible hardware for a professional, matched look.
Reliability Restoration: Replaces worn striker, extractor, and spring components to eliminate light strikes and extraction failures.
Value for Armorers & Builders: Economical way to refresh a slide or complete a custom slide build with premium parts.
Straightforward Upgrade: Designed for competent armorers and experienced DIYers to install with standard armorer tools.
Performance & Practical Advantages
Consistent Ignition: New striker and striker spring restore predictable primer contact and reduce misfires.
Improved Extraction: Fresh stainless extractor and spring increase extraction reliability and reduce stovepipe/ejection issues.
Longer Service Life: Hardened components and robust springs are better suited for repeated range sessions and training cycles.
Matched Aesthetics: Black PVD hardware presents a cohesive, low-reflective appearance when visible on the slide.
Installation & Armorer Guidance
Recommended Skill Level: Suitable for experienced armorers or competent DIY technicians familiar with Sig P320/P365 style slide disassembly. If you are not comfortable working on firearm internals, have a qualified gunsmith perform the install.
Tools Needed: Punch set, bench block, non-marring hammer, Torx/Allen drivers (if applicable), cleaning solvents, and light lubricants.
Procedure Summary:
Ensure the pistol is cleared and unloaded.
Remove the slide assembly from the frame per Sig instructions.
Disassemble the slide and remove factory parts to be replaced.
Install Rival Arms components per service manual directions, paying special attention to striker/safety orientation and extractor seating.
Reassemble, perform a dry function check, and conduct a supervised live-fire test to verify reliability.
Caveat: If your slide has aftermarket modifications (optic cuts, custom extractors, or altered geometry), verify compatibility before installation.
Maintenance & Care
Clean and remove carbon from the striker channel and extractor pocket during routine maintenance.
Lubricate recommended contact points lightly after reassembly to ensure smooth cycling.
Inspect springs periodically and replace if signs of fatigue appear — high round-count pistols benefit from scheduled spring replacement.
Black PVD finish is durable but avoid abrasive chemicals that can degrade coatings.
Who Should Buy the RA42P002A?
P365 owners experiencing light strikes, inconsistent extraction, or worn slide components.
Armorers and armories maintaining duty or training fleets.
Custom slide builders finishing a P365 slide with matched, corrosion-resistant internals.
Shooters who want a cost-effective way to extend the service life of their micro-compact carry pistol.
