Grey Ghost Precision Slide Completion Kit Sig P320

Building a custom P320 slide assembly? The Grey Ghost Precision Slide Completion Kit includes the small internal parts that turn a bare slide into a functioning unit. This kit covers 9mm slides and works with both GGP aftermarket slides and SIG OEM 320 Full-size, Compact, and Carry platforms — giving you flexibility whether you're working with factory SIG components or upgrading to a precision-built alternative.

If you're assembling a P320 from parts, wrestling with individual springs and pins can slow you down. This kit consolidates the striker assembly, extractor, extractor pin, extractor spring, and back plate into one package, eliminating the hunt through suppliers and reducing the odds of mixing up small components. It's straightforward: source your slide and frame, add this completion kit, and dial in your trigger and controls.

GGP's kit works across multiple P320 configurations, so whether you're finishing a full-size duty build, a compact EDC slide, or experimenting with different frame sizes, you've got compatible parts on hand. Like any quality parts kit, this one rewards attention during assembly — take your time, reference a build guide if you're new to the platform, and you'll have reliable function.
