Introducing the Sharps Bros 365X-Improved slide: an improved alternative for the OEM Sig Sauer P365 slide. With its integrated compensator, their slide provides what Sharps Bros consider the ideal length for the P365. The Sharps Bros 365X-Improved slide is about 1/2" longer than the OEM P365/P365X slide and about .15" shorter than the XL or X-Macro length, a perfect balance of form and function. RSR -
