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 Iron Sight Slide for the SIG P365 XL pistol offers the quality, robustness, and ergonomic enhancements of our slides for Glock pistols. Deep and wide front and rear cocking serrations give you an excellent non-slip grasp for a quick press check or to rack the slide under any conditions. The slide's edges have been beveled and de-horned to prevent snagging on a holster or clothing.

The Iron Sight 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! The window is a great way to show off an aftermarket barrel with a contrasting finish, fluting, spirals, flames, or some other exterior pattern. Or you can get your slide with a Solid top, no window. Both versions come with factory front and rear sight dovetails.


Fits the SIG Sauer P365 XL FCU & grip modules

Large front / rear cocking serrations

Factory sight dovetails

Tough, non-reflective Black Nitride finish

The Brownells Iron Sight Slide for SIG P365 XL is perfect for upgrading an existing factory P365 XL or for your own custom build. Each slide is precision machined from a billet of 17-4 stainless steel for precise fit to a SIG P365 FCU and grip module. A hard, non-reflective Black Nitride finish protects the slide from surface wear and corrosion.

Brownells Gun Tech™ Note: Our Iron Sight 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.
