MCarbo Sig Sauer P365 Stainless Compensated Slide with Ported Barrel

Sig Sauer P365 XL Compensated Slide with Ported Barrel

Upgrade your Sig Sauer P365 or P365X with the premium P365 XL Compensated Slide with Ported Barrel, engineered for superior control, accuracy, and reliability. Now on sale from $549.99 to $499.99. Expertly CNC precision machined from 17-4 PH Stainless Steel and hardened to H900, this slide-and-barrel combo delivers unmatched strength and wear resistance with a sleek Black Nitride finish. Precision tolerances enhance accuracy and performance, while aggressive front and rear serrations ensure a confident grip during press checks and slide manipulation.

The ported 3.1" barrel and ported slide cuts work together to reduce weight and tame felt recoil, allowing faster follow-up shots and consistent sight alignment. The slide includes an RMSC optic cut footprint, supporting popular optics like Shield RMS, SIG Romeo Zero, and Holosun 407k, with reinforced mounting tabs to minimize shear stress on screws. Rear sights sit behind the optic cut for a traditional sight picture. An optic plate cover and mounting screws are included.

Compatibility: Works with all P365 grip modules and newer-style P365 extractors. Requires an XL Guide Rod. Not compatible with .380 models.
