Norsso Sig Sauer P320C Vector RMR Slide - Black Nitride



The Vector is a Sig Sauer P320 compact/carry compatible aftermarket slide that Norsso manufacture in-house at their shop in Las Vegas. They start with a 17-4 stainless steel billet and CNC mill the critical dimensions creating a slide blank. To achieve the ability to modify the exterior of the slide, they leave mass in the forward area of the slide near the muzzle. This allows them to remove more material in other areas of the slide for porting, customization and enhanced serrations. Without the redesigned slide blank, you run the risk of an unreliable firearm from large amounts of slide milling. Heavily modifying the factory compact P320 slide is generally frowned upon in the Sig community. For this reason and the standard forward serrations that are provided from the factory, Norsso designed an aftermarket solution.

The main features of the exterior slide milling are the 3D machined ports around the nose. This technique of customization allows for large eye catching features while controlling the slide structure and areas of material removal. Once you go 3D it's hard to go back to the conventional method of porting a slide. Aesthetically they don't compare. Additionally they added enhanced serrations for easier manipulation of the slide.
