With its integrated three port compensator, our slide provides what we consider the ideal length for the P365. The Sharps Bros 365X-Improved slide is about 1/2in longer than the OEM P365/P365X slide and about .15in shorter than the XL or X-Macro length, a perfect balance of form and function. The Sharps Bros 365X-Improved slide offers a clean, bold design with ergonomic slide serrations, slide porting, and an integrated compensator. The milled optics cut sits just forward of the rear sight, so you can install and remove your optic without disturbing your open rear sight. This design also allows for the installation of suppressor-height sights for co-witnessing. Specifications for Sharps Bros.
