SIG Sauer P320-XFIVE Pro-Cut Complete Slide – 9mm, 5" Barrel, Black Nitron (8901572)

This is the factory P320-XFIVE Pro-Cut complete slide assembly — a slide package only, not a full pistol. SIG builds it around a 5-inch match-grade barrel, a stainless steel slide in Black Nitron, a fiber optic front with adjustable rear, and a PRO optic footprint ready for optics such as the ROMEO2 or ROMEO-X PRO when you remove the rear sight. SIG part 8901572, UPC 798681692712. This listing is for the complete slide assembly only.

What You Get in the Box

• Complete slide assembly with 5.0" barrel
• Solid steel guide rod
• Two recoil springs — a 14 lb 1911-style spring plus an additional 12 lb spring

Optic Ready on the PRO Footprint

The adjustable rear sight can be removed so you can mount a PRO-footprint optic. Iron-sight shooters keep the factory fiber front and adjustable rear. No electro-optic is installed on this SKU.
