The Real M17 is a precision-engineered slide assembly designed for the SIG P320 platform. It’s for builders who demand OEM-level fitment and modern aesthetics without the factory premium. Since we started carrying it in early 2026, it’s become a consistent reorder item for us, moving over 50 units to date. The key benefit is direct compatibility and a clean, aggressive look that upgrades your build instantly.

Frequently Asked Questions
Does this include sights or an optic plate?
This is a slide assembly only. It includes a removable cover plate for the optic cut, but iron sights and the specific optic plate must be purchased separately to match your chosen red dot.
Will this fit my aftermarket P320 frame?
It is machined to OEM SIG specifications. While it fits all OEM frames perfectly, we had one return where a customer found it “too tight” on a specific aftermarket frame. For guaranteed fitment, use an OEM SIG P320 grip module.
What parts do I need to complete my build?
You will need a P320 FCU (Fire Control Unit), a compatible barrel and recoil spring assembly, a grip module, and sights. This slide is the core component that ties the build together.
