The Sig Sauer P365XL slide assembly (brand part no. 8900987) is a factory replacement slide built specifically for P365XL grip modules and the P365XL’s 3.7-inch barrel. Machined from stainless steel and finished in a coyote brown Nitron coating, it comes fitted with Sig’s XRAY3 day/night sights along with a removable sight plate cover that is ready to accept a micro red dot such as the ROMEOZero. This slide does not include the recoil spring, guide rod, or barrel, and it is not compatible with the ported barrel option, so it is best suited as a direct factory slide swap or repair part for an existing P365XL.
