5X/Mk1C - P365XL Ported Slide and Barrel.
Machined in one continuous operation on our 5-axis vertical machining centers from a premium USA made 17-4SS slide blank, our 5X series of slides are designed to be a reliable, turnkey upgrade for your stock Sig P365XL or P365 XMacro slide.
The 5X/Mk1 features full wrap around directional sawtooth serrations. The rear serrations are cut to an enhanced depth and feature sawtooth leading edges for extreme traction. These slides are available with your choice of optic cut and surface finish.
These slides are stripped, ready for you to install your OEM internals from your existing slide. Any iron sights, slide internals, or optics purchased with the slide will be installed prior to shipment at no charge.
Every slide will be test fired with Sig OEM internals prior to shipment. This slide is guaranteed to function with Sig OEM internals (including Sig factory barrel and factory recoil spring) on a Sig P365 factory frame. Use of any aftermarket (non-Sig OEM) parts or internals will void this function guarantee and warranty.
This slide carries a limited lifetime warranty. Please see our FAQ.
Note: Barrel will be finished in Black Nitride by default. Stainless barrel show in pictures is just for demonstration to better show porting geometry.
