Description
Building or rebuilding a slide for your Glock 43, 43X, or 48 means hunting down a handful of small internal parts, and that gets old fast. This Rival Arms kit takes the guesswork out by bundling all the essential guts into one package, so you can go from a stripped slide to a working one without ordering pieces one at a time from three different places.
What Goes Into the Rival Arms 43/43X/48 Slide Kit
Inside you'll find the RA precision striker, striker spring and spring cups, the striker safety and its spring, a spacer sleeve, the extractor with its depressor plunger and plunger spring, the spring loaded bearing, and a back cover plate. Rival Arms runs a PVD coating on select parts and machines others from solid stainless steel billet, which is the kind of attention that keeps things running clean and consistent shot after shot. Worth noting for anyone new to these guns: single stack 43/43X/48 slides don't use a channel liner, so you won't find or need one here.
Getting the Rival Arms Completion Kit Installed
This is a no-gunsmith-required job for anyone comfortable taking a Glock striker assembly apart. A punch, a bit of patience, and a good look at how the OEM parts came out will get you there. Take your time seating the extractor and depressor plunger correctly, and do a proper function check before you head to the range, same as you would with any slide work.
Once the internals are set, all that's left is a barrel, a guide rod assembly, your sights, and a completed lower. Then you've got a finished pistol ready to run. It's a straightforward way to breathe life into an aftermarket or stripped slide, and it pairs well with a custom build where you want quality internals instead of scavenging factory pieces.

Frequently Asked Questions
What does the Rival Arms slide completion kit fit?
It's built for the single stack Glock 43, 43X, and 48 in 9mm Luger. These share the same slide internals, so one kit covers all three. Double-check your slide is one of these models before ordering.
Do I need a gunsmith to install this slide completion kit?
No. It's designed as a no-gunsmith-required install for anyone comfortable disassembling and reassembling a Glock striker assembly. A punch and some patience get the job done, and you'll want to run a function check afterward to confirm everything seats and cycles right.
Does this kit include a slide channel liner?
No, and that's by design. The single stack 43/43X/48 slides don't use or require a channel liner, unlike some of the double stack Glock kits. So you're not missing a part if you don't see one in the box.
What else do I need to finish my build after installing this kit?
Once the internals are in, you'll add a barrel, a guide rod assembly, your sights, and a completed lower to have a working pistol. This kit handles the internal slide components so you don't have to source the striker, extractor, and small springs separately.
