Ultimate modularity means infinite choices for your Sig P320 C build. If you are ready to give your FCU the Killer edge, our Velocity Defense for Sig P320 C V2 slide awaits. The Velocity Defense V2 slide has no window cutouts to slow you down. You will still find our forward and rear E.G.F. cuts. Functional and precise racking that can help control debris from getting into the slide, or keep you fully operational no matter what situation you find yourself in. The Velocity Defense V2 slide will always have you covered.
Why the Velocity Defense slide?
The Velocity Defense slide is lighter weight, a high-quality upgrade to your FCU, even without the window cuts! The slide features a dual cut optic pattern which allows you to mount either an RMR or delta point pro with no mounting plate.
What is an E.G.F. Cut?
Our “enhanced grip feature” cuts will change how you rack your firearm. E.G.F. Cuts provide a positive wall that you can push against when racking your slide instead of relying only on traditional serration cuts. E.G.F. Cuts are located at the front and back of our slide, so however you prefer to rack your firearm, a perfect grip is always there.

As far as RDS, or Optics go. Our slide is dual cut to either support the Leupold Delta Point Pro or the Trijicon RMR. The RMR is a common RDS footprint where other systems can fit, such as certain Holosun models. (Please check with your optics manufacture to confirm compatibility with our DDP/RMR footprint.)

My first Killer Innovations product and I’m more than pleased. Although this slide is a beautiful piece of art, I really bought it for its more practical and well thought out slide serrations and cuts related to gun handling compared to OEM. It does not disappoint. 250 rounds in so far with zero stoppages or issues, and very minimal contact wear. I plan on running another 250 rounds through it and then calling it for my EDC.
