Sharps Bros 365X-Improved Slide – RMSc Optic Cut & Integrated Compensator

Upgrade your Sig P365X with the Sharps Bros 365X-Improved Slide, precision-engineered for shooters who demand more than stock performance. This slide combines function and style with a 3-port integrated compensator, RMSc optic cut, and forward-thinking ergonomics — all without sacrificing concealability.

Machined from heat-treated 416 stainless steel and finished in durable black nitride, the slide is about ½” longer than the OEM P365/P365X slide, striking the perfect balance between the compact P365 and full-size X-Macro length. The porting and compensator work together to reduce muzzle rise, allowing for faster follow-up shots and better control in high-stress conditions.

Designed to co-witness with suppressor-height sights, the optic cut sits just forward of the rear sight so you can swap your red dot without disturbing your iron sight zero. Whether you're upgrading for EDC, range work, or competitive shooting, this slide is a premium drop-in solution.

🔧 Key Features:

• Compatible with Sig P365X (also fits standard P365 frames)

• Integrated 3-port compensator for reduced muzzle rise

• RMSc optic cut – fits Shield RMSc, SIG Romeo Zero, Holosun 407K/507K

❓ Frequently Asked Questions (FAQ)

Q: Will this slide fit a standard Sig P365 frame?
A: Yes. While designed for the P365X, this slide is also compatible with the standard P365 and allows you to use a longer slide on a smaller frame.

Q: What optics are compatible with the RMSc cut?
A: It fits RMSc-footprint optics such as the Shield RMSc, SIG Romeo Zero, Holosun 407K, and 507K without the need for additional plates or adapters.

Q: Do I need a threaded barrel for the compensator?
A: No. The compensator is machined directly into the slide, so no threaded barrel or timing is needed.

Q: Can I co-witness with my backup sights?
A: Yes. The optic cut is positioned to allow suppressor-height sights to co-witness with your red dot, offering redundancy and quicker target transitions.

Q: Does the slide come with internal parts or sights installed?
A: No. The Sharps 365X-Improved slide is sold stripped, allowing you to customize with your preferred internals and sights.
