When purchasing Brownells or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

The Brownells slide for the SIG P365 XL comes with a built-in mounting slot for the Holosun 507K red dot sight. The affordable, feature-rich, ultra-compact 507K is the perfect red dot for the compact, versatile SIG Sauer P365 XL pistol platform. Although some mount footprints for other manufacturers' red dot sights can work for the Holosun 507K, the mounting slot on our slide is cut to fit the exact dimensions of the sight. This results in a rock-solid sight installation that will not shift under recoil.

Our Holosun 507K Cut Slide for SIG P365 XL offers all the quality, robustness, and ergonomic enhancements of our popular slides for Glock pistols. It is perfect for upgrading an existing factory P365 XL or for your own custom build. Each slide is precision machined from a billet of stainless steel for precise fit to the SIG P365 FCU and grip module. A tough non-reflective Black Nitride finish protects the slide from surface wear and corrosion.

Front and rear cocking serrations are wide and deep enough to give you a non-slip grasp to rack the slide under any conditions. Edges have been beveled and de-horned to prevent snagging on a holster or clothing. Supplementing the Holosun 507K mounting slot are factory dovetails for front and rear "iron, sights as backups should your red dot fail (which is pretty unlikely!).

The Brownells Holosun 507K Cut Slide for SIG P365 XL is available with a Window cut into the forward top of the slide for weight reduction and because it just looks cool! Or you can get your slide with a Solid top, no window.

Brownells Gun Tech™ Note: Our Holosun 507K Cut Slide for SIG P365 XL consists of the bare slide only. You will need to retain your pistol's existing internal parts or use aftermarket parts.
