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 Mfg: Brownells
