The Norsso slide is milled for the Aimpoint ACRO P-2 footprint (closed-emitter) and includes front and rear serrations, an external extractor, and a cover plate with an integrated serrated square-notch rear sight. A metal, dovetailed front post complements the iron sight setup for a clean, durable sight picture.
The Norsso threaded barrel is steel, measures 4.7 inches, and includes a thread protector. This setup adds versatility while maintaining the full-size balance and reliability the P320 platform is known for.
The Grayguns X-Full grip module in black brings laser-sculpted texture for secure purchase and a flared magwell to speed reloads. A flat-faced trigger and left-side magazine release round out the ergonomic, control-focused configuration.
