SHARPS BROS
The Sharps Bros 365XL Slide with Integrated Compensator is a precision-engineered upgrade for shooters running the Sig Sauer P365 platform who want better control and a longer sight radius without going full X-Macro. Built from 416 stainless steel, heat-treated and finished in black nitride, this slide splits the difference perfectly—about half an inch longer than the factory P365/P365X but roughly a tenth of an inch shorter than XL or X-Macro lengths. That balance means you get the benefits of a compensator and extended sight plane while keeping your carry gun reasonably compact.
The integrated three-port compensator works with factory P365X barrel lengths (3.1") and plays nicely with your existing P365 or P365X recoil spring, so no guessing on compatibility. Sharps Bros cut ergonomic serrations front and rear for confident press checks and slide racking—especially useful if you're running it suppressed or in a duty context. At 6.08" in overall length, it's a sweet spot for shooters balancing shootability with concealment. The slide comes stripped, so you'll be adding your own sights and internals; that's standard for precision builds and lets you dial in your exact setup.
Optics-ready out of the box, the slide accepts the Shield RMSc, Sig Romeo Zero, and Holosun HS407K or HS507K footprints—your choice of proven red dot platforms. An optic cover plate is included, so you're protected if you want to run iron sights temporarily or during storage. Whether you're building a precision range gun, a carry gun with an edge, or a duty platform, this slide gives you the fit and function that factory trim sometimes leaves on the table.
