Shadow Systems Slide Completion Kit without Guide Rod fits Glock G17 G19 G34 and G26 Gen 1-4

The Shadow Systems Slide Completion Kit (SGK-1004) gives you the slide-mounted internals needed to finish a Glock upper without sourcing each part separately. It fits the Glock G17, G19, G34, and G26 in Gen 1 through Gen 4 configurations, which covers most of the common double-stack 9mm and subcompact builds people are assembling. This kit ships without a guide rod, so it's aimed at builders who already have a recoil assembly or plan to run an aftermarket setup. If you're putting together a stripped slide, this is the parts package that gets you to a functioning upper.

A slide completion kit covers the firing pin assembly, firing pin spring and spacer sleeve, the firing pin safety and its spring, the extractor and extractor depressor plunger assembly, and the slide cover plate — the small components that have to go inside a bare slide before it cycles. Because the kit excludes the guide rod, you keep the freedom to pair it with a stock recoil assembly or a tungsten or stainless aftermarket setup. We carry separate tungsten guide rod assemblies for those who want to round out the build. Fitment spans Gen 1-4 frames, so the same kit works across the G17, G19, G34, and G26 platforms from Shadow Systems dba Shadow Gunworks.

This is a build kit for anyone finishing a stripped Glock slide — a new aftermarket slide, a milled optic-cut slide, or a replacement for worn factory internals. Pair it with a complete slide and a guide rod and you have a working upper ready to mate to a frame. If you'd rather buy a slide that arrives assembled, look at our Glock 19 cut slides, or browse the full slides and slide parts selection to match components to your build.
