A Look at Sig's NEW P320 3.9" Raze Custom Works Slide

If you’re hoping to build, upgrade, or replace your Sig P320 slide, you’re in luck. Sig Sauer recently announced the latest addition to their customization options for the P320: the 3.9” Raze Custom Works Slide Assembly.

The brand’s latest slide assembly offering is coated with a durable Nitron finish, is fitted with XRAY3 Day/Night Suppressor height sights, and comes optics ready. It also features a removable flush-fit optics plate with top accessible screws, making it easier to mount optics to this popular pistol.

Let’s take a look at the details of this new custom slide.

Compatibility

The 3.9" Raze Custom Works Slide is designed to fit the P320 compact (non-X-Series), full size, and carry (X-Series and non-X-Series) grip modules. It can be used with any of Sig’s standard 9mm, 3.9” non-threaded barrels or a 4.6” threaded barrel.

It is important to note that the new slide assembly is only compatible with 9mm barrels and will not work with the .40, .357, or .45 variations. Fortunately, Sig has noted that adding the new slide to your firearm will not void its warranty.

Features

Optic Ready: The new 3.9" Raze Custom Works Slide is designed to be optics ready and is compatible with the ROMEO1-PRO, ROMEO2, Delta Point Pro, and RMR footprint (which requires a sealing plate).

Sights: The new slide assembly comes standard with Sig’s XRAY3 day and night suppressor height sights, a 3-dot tritium system designed to provide illumination in low-light conditions.

Material and Finish: The 3.9” Raze Custom Works Slide is made from stainless steel and is coated with a durable scratch and corrosion-resistant Nitron finish.

Optics Plate: Sig’s new slide assembly is complete with a removable flush-fit optics plate. It is designed with top accessible screws, which makes removing the optics cover plate easy, so you can mount new optics without much difficulty.
