Whether you're finishing a custom build or refreshing your existing slide, the GGP Slide Completion Kit gives you the essential internal parts without the unnecessary markup. Most of the components are machined from 17-4 stainless steel bar stock, so you're working with materials built to last.
This kit includes the striker assembly, extractor, extractor pin, extractor spring, extractor pin plus, and a metal backplate. That covers the moving parts and fasteners you need to get a fully functional slide. It works with both 9mm GGP320 slides in full-size and compact versions, plus it's compatible with factory SIG P320 OEM slides across full-size, compact, and carry sizes. Installation requires breaking the slide down beyond a simple field strip, and if you're not comfortable with that level of work, having a gunsmith handle it is the smart move.
Keep in mind this kit does not include the recoil rod assembly, barrel, or sights. You'll need to source those separately depending on what you're building. Most builders already have preferences on these parts anyway.
One thing that stands out to people who've used this kit is the metal backplate. Factory SIG kits come with plastic, but you're getting aluminum here instead. It's a small detail that makes the slide feel more refined when you work with it, and it'll hold up better over time.
Yes, the kit is designed for compatibility with factory SIG OEM P320 slides in full-size, compact, and carry sizes. It also works with GGP320 full-size and compact slides. Just make sure you have all the tools needed for a more involved disassembly before starting.
You'll still need a barrel, recoil rod assembly, and rear sight to finish the job. The kit handles the internal moving parts, but those three items need to come from your supplier of choice depending on your build preferences.
The main materials difference is that most GGP components are machined from 17-4 stainless steel bar stock, which provides reliability built in. The backplate in particular gets attention from builders because it's metal instead of plastic like the factory version.
Installation requires disassembly beyond a simple field strip, so if you're new to internal slide work, having a qualified gunsmith do the install is the safe choice. If you've done this work before, the installation is straightforward.
