The Sig Sauer P365/P365XL/P365X 9mm Nitride Black Slide with integrated compensator is purpose-built for shooters who want factory-engineered recoil management without the hassle of a removable comp. This is a complete slide assembly—not a bare slide—that drops onto your frame with front and rear XRAY3 Day/Night suppressor-height sights already installed. The integrated compensator is tuned to reduce muzzle flip and felt recoil, and because it's forged into the slide itself, it stays put through disassembly and field cleaning, plays nice with standard P365XL holsters, and eliminates the fidgety parts pile that comes with add-on compensators.
The slide is machined from stainless steel with Nitron finish—hard-wearing and corrosion-resistant—and includes a loaded chamber indicator for status checks without rack-and-peek. The top is milled optic-ready with a removable sight plate that accepts the compact RX footprint used by Sig's ROMEOZERO and ROMEOZERO Elite red dots, as well as other optics like the RMSc and 507K. This is real flexibility: you can run irons straight out of the box, add a micro red dot later, or even cowitness them.
A critical note: you'll need a 3.1-inch non-ported barrel and a P365XL recoil spring assembly to make this work—the slide alone is incomplete. Do not use ported barrels or .380 AUTO parts; this is a 9mm Luger platform only. If you're retrofitting an existing P365 frame or building a micro 9 that actually points flat and soaks up recoil, this slide does the heavy lifting.

You'll need a 3.1-inch non-ported barrel and a P365XL recoil spring assembly. Do not use ported barrels—they are not compatible with this slide.
No. This slide is 9mm Luger only and is not compatible with .380 AUTO components. Verify your frame and all components are 9mm before assembly.
The slide accepts optics with the compact RX footprint, including the Sig ROMEOZERO and ROMEOZERO Elite, as well as the Leupold RMSc, Shield RMS-c, and Holosun 507K.
The XRAY3 sights are suppressor height. Cowitness will depend on your specific red dot choice and height—consult the optic manufacturer's specifications for your setup.
