Looks better on the Sig P320 by texasguns, Verified Owner, March 24, 2022
The slide is awesome and looks bad a$$. Great quality slide for the Sig P320 and the best looking one I have see online. I almost bought a different one but stumbled on this site and there it was. I pulled the trigger and got it fast.

Amazing slide. Paired with a grey ghost completion kit. Put 400+ rounds threw this bad MF and not a single malfunction. Looks sick and helps the barrel cool down. Great purchase.

Product Info for Killer Innovations Sig P320C V1 Slide

The newest addition to our P320 lineup is our KAC P320C Slide Package. These slides feature an aggressively serrated back-end for better snag free draws and slide manipulation. In addition to the aggressively serrated back-end, this slide package comes with a backup RMR shim & spring (sold separately). This shim is required when using the KAC P320C Slide Kit, as the slide serrations are long enough to prevent snags with some brass trays and poor hand-fit slides. Since this slide is made of an aluminum, it will withstand thousands of strikes with the RMR shim included. Each P320C KAC Slide package comes with a coverplate. Since KAC slides are made of an incredibly strong, pressed steel, they have been tested over and over again for strength, durability, impact resistance and harmonics. They are precision machined to near-perfect tolerances with industry-quality standards and materials. Each slide also comes with a white back-strap decal for easy snag free draws. These slides also feature an aggressive front end for greater slide/ejection port clearance. These slides also include a RMR shim. These shims are essential for use with RMRs as the RMR backstrap protrudes out a small amount of the snag preventing them from sliding out of the RMR channels during operation. These shims are included in the package with all Killer slides and are designed to prevent any slide damage while syncing the RMR.image
