Key Features & Benefits
Direct Fit for Glock 42 (.380 ACP): Engineered to match factory dimensions for drop-in compatibility with standard Glock 42 slides.
Premium Stainless Construction: Corrosion-resistant stainless components for longevity and resistance to wear from high round counts and cleaning.
Black PVD Finish: Durable, low-glare coating that protects the surface and gives a professional, tactical look.
Improved Wear Resistance: Upgraded parts reduce galling and extend service life compared with worn OEM components.
Smoother Function: Precision machining and tighter tolerances promote reliable slide operation, consistent lock-up, and improved cycling.
Straightforward Installation: Designed for armorers and competent DIY builders — replaces worn slide internals with minimal fitting on standard Glock 42 slides.
Typical Kit Contents (May Vary by Batch)
While exact included parts vary by production run and vendor packaging, a standard Rival Arms slide completion kit for Glock 42 often includes precision replacements for many of the slide’s wear-critical components, such as:
Extractor and extractor spring / insert (stainless)
Firing pin and firing pin spring (stainless)
Slide rails / rail inserts where applicable (stainless components or wear surfaces)
Firing pin safety / safety spring
Plunger cups, springs, and small slide pins as required
Slide cover plate or other slide-specific hardware finished in Black PVD
Note: Confirm the exact list of components with the seller or product packaging prior to purchase — some kits are tailored to either complete replacement or specific performance upgrades.
Performance & Practical Advantages
Restore Function on Worn Slides: If your Glock 42 slide shows extraction issues, light strikes, or inconsistent firing-pin function due to worn parts, this kit is a practical way to refresh the slide without replacing the entire slide or firearm.
Upgrade Corrosion Resistance: Stainless components plus PVD finish resist rust and pitting better than ordinary coated steels — great for range use or humid storage.
Aesthetic Upgrade: The Black PVD finish gives the slide internals and visible hardware a matched, professional look that complements tactical or custom builds.
Value for Custom Builds: For builders converting or customizing Glock 42 slides, this kit supplies premium internal gear that enhances longevity and reliability.
Installation & Armorer Notes
Skill Level: Intended for armorers or experienced DIY builders familiar with Glock disassembly and slide internals. If you are not comfortable working on firearm internals, consult a qualified gunsmith.
Tools Needed: Standard Glock armorer tools — small punches, bench block, non-marring mallet, torque/punch set, and appropriate cleaning/lubrication supplies.
Procedure: Disassemble the slide per Glock’s service manual, replace worn components with kit parts, reassemble and perform function checks (firing pin safety, trigger reset, dry-fire check) before live-fire testing.
Verification: After installation, perform a thorough function and safety check and then test-fire to ensure reliable ignition and proper extraction/ejection.
Caution: Always follow safety protocols: clear the firearm, remove magazine, verify chamber empty, and work in a safe, well-lit area.
Compatibility & Fitment
Model Fit: Specifically designed for Glock 42 slides (.380 ACP).
Not Universal: Not intended for other Glock models (Glock 43/43X, G42 Gen variations with aftermarket slide mods may require verification). If your slide has non-standard machining (optic cuts, custom extractors), check fitment before installation.
Check Before Purchase: Verify kit contents and model compatibility with the vendor to ensure the kit addresses the components you need.
Maintenance & Care
Cleaning: Keep components free of heavy carbon and fouling — clean the slide and parts using approved solvents and brushes. PVD finish is durable but avoid harsh abrasives to keep the finish intact.
Lubrication: Apply a light film of appropriate firearm lubricant to moving parts and slide rails following reassembly.
Inspection: Periodically check springs and small parts for wear or deformation; replace as necessary to maintain reliability.
Storage: Store assembled slides and spare parts in a cool, dry place to minimize corrosion risk even with corrosion-resistant materials.
