Sig Sauer P365 9mm Luger Slide Completion Kit - Fits P365/P365X/P365XL

The Sig Sauer P365 Slide Completion Kit (Sig part 8900980) supplies the factory internal components needed to complete or rebuild the slide of a Sig P365, P365X, or P365XL pistol in 9mm Luger. It is designed for builders and gunsmiths who already have a barrel, sights, and recoil assembly on hand and want OEM-spec slide internals to finish out the slide the rest of the way.

This kit includes all of the corrosion-resistant replacement parts housed inside the slide itself, the same internals Sig Sauer installs on a factory-complete P365-family pistol. Using genuine Sig Sauer components keeps tolerances and function to factory spec, so the finished slide runs reliably with the standard P365, P365X, and P365XL grip modules and fire control group. The corrosion-resistant finish stands up to daily carry sweat, holster wear, and range-day moisture without premature rust.

The P365 Slide Completion Kit is intended for the 9mm Luger P365, P365X, and P365XL only. The barrel, sights, and recoil assembly are sold separately, giving the builder flexibility to pair the slide internals with their preferred barrel length, sights, and recoil setup. Sig Sauer OEM slide parts are the correct choice whenever you want factory fit, function, and finish without compromise.
