P320 Reptile Compact

The Reptile is a Sig Sauer P320 compact/carry compatible aftermarket slide that we manufacture in-house at our shop in Las Vegas. We 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, we leave mass in the forward area of the slide near the muzzle. This allows us 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, we designed an aftermarket solution. 
This design incorporates features that are cutting edge to the slide customization market. For ease of slide manipulation, we've added angled forward and top serrations to aid in press checks and slide racking. The top serrations also include a beveled edge to blend the serrations into the chamfers creating a scale like texture. The front of the slide has multifaceted contours giving the slide a streamlined look removing any sharp edges and smoothing the corners. The most appealing feature of the slide is the side windows. they are aesthetically pleasing with varying surfaced slopes that catch the eye. These are created using 3D CNC machining technology that provide an extra level of depth to the slide.

Bought and installed on my Sig x Carry. Fit and finish are flawless. Looks amazing installed. Rmr fits like a glove. Absolutely love it, changes the look of the piece in a radical way! Battle hardened finish really makes the lines and details pop!!!

Anyone with a p320 needs a Norsso slide.
