P320 Modern Classic Slide, 3.9”
$600.00 – $650.00
Custom Modern Classic P320 slide designed by Bruce Gray and the Grayguns team. This slide features a refined, classic look that complements the modern design of the SIG Sauer® P320. This is the 3.9-inch barrel version created by our team.
Includes custom slide and all internals. Options available will vary.
Description
Our custom Modern Classic P320 3.9-inch slide package focuses first on the weight and balance of the slide. We’ve introduced a traditional 1911 spin with utility-driven serrations in strategic areas. Available in a Black Diamond-Like Carbon (DLC) finish. Each custom slide features the iconic Grayguns logo.
As a classic gunsmith, Bruce didn’t want his slide to resemble or feel like a wood rasp out of a woodshop. They went through many iterations but settled on something traditional for this modern sporting pistol.
Slide Package Includes
- Custom Grayguns Modern Classic designed slide
- OEM internals (Ejector, Striker Assembly, and Slide Cap)
- Choice of optic cut or OEM dovetails only
P320 Modern Classic Slide – 3.9-inch – Additional Information
You can directly mount one of our red dot options to the slide. There is no need for an adaptor plate.
Fit Guide
If you select the RMR cut, the Trijicon RMR optic will fit fine. Although the Trijicon SRO has the same hole pattern footprint as the RMR, the SRO optic is bigger and will slightly overlap the ejection port on the P320 3.9″ slides.
