Firing pin / striker and striker spring (stainless steel)
Firing pin safety and safety spring
Extractor and extractor spring / insert (stainless components where applicable)
Firing pin channel liner or cover plate (if applicable)
Slide cover plate or slide-specific hardware with Black PVD finish
Plunger cups, springs, and small slide springs / pins needed for a full slide refresh
These components are manufactured to Rival Arms’ tolerances and finished with Black PVD for improved wear resistance and a matched appearance.
Why Choose This Slide Completion Kit?
Tailored Fit: Engineered specifically for the Sig P320 slide geometry to ensure direct fit and correct function.
Durable Materials: Stainless steel components resist corrosion and pitting better than coated mild steels—especially important for high-round-count training and frequent maintenance.
Black PVD Finish: Adds a low-glare, scratch-resistant finish to visible parts and protects mating surfaces during cleaning and use.
Restore & Improve Reliability: Replace worn or deformed parts that can cause light strikes, failures to extract/eject, or inconsistent primer strikes.
Value for Armorers: An efficient way to refresh service pistols or stocking dependable replacement parts for armory maintenance.
Performance & Practical Benefits
Reliable Ignition: New firing-pin/striker components restore consistent primer contact and reduce light-strike incidents.
Improved Extraction: Fresh extractors and springs help ensure consistent extraction and ejection, lowering the chance of stoppages due to worn parts.
Extended Service Life: Hardened stainless parts and robust springs stand up to extended use and repeated cleaning cycles without premature wear.
Sleek, Matched Look: Black PVD hardware gives you a cohesive, low-glare appearance aligned with modern carry aesthetics.
Installation & Armorer Notes
Skill Level: Intended for experienced armorers or competent DIYers comfortable with pistol slide disassembly/reassembly. If you are not confident in working on firearm internals, have a qualified gunsmith perform the installation.
Tools Required: Pin punches, bench block, small hammer or non-marring tool, appropriate Torx/Allen drivers (if applicable), and proper cleaning/lubrication supplies.
Procedure: Follow Sig Sauer’s service manual procedures for slide removal, disassembly, part replacement, and reassembly. After installation, perform a full function check (striker/firing-pin safety, trigger reset, dry-fire checks) and confirm reliable cycling during live-fire testing.
Caution: Ensure the firearm is unloaded and follow all firearm safety protocols at every step.
Compatibility & Fitment
Model Fit: Specifically designed for Sig P320 slides—verify generation (and whether your pistol uses any special slide cuts or aftermarket modifications) before purchase.
Aftermarket Slides: If you have a modified slide (optic cuts, custom extractor geometry, or non-standard machining), confirm compatibility or consult Rival Arms/vendor documentation. Some highly modified slides may require gunsmith verification.
Not Universal: This kit is not intended for non-P320 platforms.
Maintenance & Care
Cleaning: Clean slide components and mating surfaces with approved solvents and brushes. Remove carbon build-up from firing-pin channel and extractor pocket.
Lubrication: Apply small amounts of high-quality firearm lubricant to recommended contact points; avoid over-lubrication which attracts fouling.
Inspection: Periodically inspect springs and small parts for wear or deformation and replace as needed to maintain reliability.
Finish Care: Black PVD is robust—clean with mild solvents and avoid abrasive polishing compounds that can wear the finish prematurely.
Ideal Applications
Armory Maintenance: Stock replacement parts for service or training pistols.
Restoration Projects: Return a worn Sig P320 slide to reliable service without replacing the entire slide.
Custom Builds: Finish a custom slide with matched, corrosion-resistant internals and a premium black aesthetic.
Range & Duty Use: Upgrade internals for pistols that see high round counts or harsh environments.
