Description: 

*These units are completed and are considered to be blemished due to cosmetics only. Some of the imperfections may include dings, dents, scratches, machine marks or a color that's not completely in spec. However, they are 100% fully functional. All blem purchases are for final sale and are non-refundable. 

The Shadow Slide was built with real-world use in mind. Designed for reliability, control, and clean execution, it features forward serrations for improved grip and handling, along with top-side striations that help reduce glare in bright conditions. The result is a slide that looks sharp, runs clean, and performs consistently under use.

Whether this is a range gun, duty setup, or a hard-run build, the Shadow Slide delivers practical performance you can rely on.

Every Shadow Slide ships fully completed and ready to run. No additional parts, no add-ons, no assembly required.

Finish Options

Black Anodize
A classic, duty-ready finish that offers a clean, low-profile look with excellent wear resistance. Ideal for users who want a timeless appearance that pairs well with any build.

FDE Cerakote
A durable ceramic coating that provides added corrosion resistance and a distinct, modern aesthetic. FDE offers a lighter, high-contrast option that stands out while still maintaining a professional, hard-use appearance.

Choose the finish that fits your build, your environment, and how you run your firearm.
