Rival Arms RA42G002A Slide Completion Kit for Glock 43/43X/48 - 9mm Luger, Black PVD Stainless Steel

Building or rebuilding a Glock 43, 43X, or 48? The Rival Arms RA42G002A Slide Completion Kit takes the guesswork out of sourcing individual components. Instead of hunting down a striker, extractor, safety, springs, and plunger separately—each from a different supplier, each with different quality standards—this kit bundles everything you need to finish your slide's internal assembly in one box. The parts are engineered to work together, which means better fit, faster build, and confidence that you're not mixing incompatible pieces. Once the slide is done, you're just a barrel, guide rod, and completed lower receiver away from a working pistol. Whether you're a custom builder, a tinkerer looking to understand your gun better, or someone doing a complete refresh, this kit cuts through the complexity.

Rival Arms manufactures each component with precision and attention to detail. The black PVD stainless steel finish is durable, corrosion-resistant, and looks sharp—no rough edges or sloppy tolerances. This is the kind of kit that works because every single part was designed to function as a system, not as an afterthought.

Compatible with single-stack Glocks (G43, G43X, G48), the kit includes the striker, extractor, safety, all necessary springs, depressor plunger, back cover plate, and precision-machined components like the RA Precision Striker, spacer sleeve, and loaded bearing. It's a complete interior—all you need to add is the barrel and lower to have a functioning firearm.

Frequently Asked Questions

Is this kit compatible with all Glock 43 variants?

Yes—the kit is designed for the Glock 43, 43X, and 48. These are all single-stack 9mm platforms with the same internal slide dimensions.

What else do I need to complete my build?

This kit covers the slide interior. You'll also need a barrel, guide rod, and a completed lower receiver (frame with trigger assembly and magazine) to have a finished, functional pistol.

Does this kit include a channel liner?

No—the single-stack slide completion kits (including this one for the G43 family) do not include or require a channel liner.

Why buy a matched kit instead of individual parts?

A kit ensures all components are engineered to work together with consistent tolerances and quality. You avoid the risk of mixing incompatible springs, strikers, or extractors, and you save the time and cost of sourcing each part separately.
