P365XL Modern Classic Slide

Custom P365XL Modern Classic slide designed by Bruce Gray and the Grayguns team. This slide features a refined, classic look that complements the modern design of the SIG Sauer® P365. This is the standard P365 version with the 3.7-inch barrel.

Includes custom slide with OEM slide internals (Striker Assembly, Striker Safety Lock, Extractor and Slide Cap). Options available will vary.

Our custom Modern Classic P365XL Slide focuses first on the weight and balance of the slide. We’ve introduced a traditional 1911 spin with utility-driven serrations in strategic areas. Available in a Black Diamond-Like Carbon (DLC) finish. Each custom slide features the iconic Grayguns logo.

As a classic gunsmith, Bruce didn’t want these P365XL slides to resemble or feel like a wood rasp out of a woodshop. They went through many iterations but settled on something traditional for this modern sporting pistol.

Package Includes

  • Custom Grayguns Modern Classic designed slide
  • OEM Slide Internals: Striker Assembly, Extractor, Striker Safety Lock, and Slide Cap
  • Slides include OEM factory dovetail cuts for a front and rear iron sight option

Available Optics and Sights

Value-Add Bonus – When selecting a slide and including an optional optic and/or iron sights, we include complimentary professional installation (a $50 value).
If you order a slide with sights or optics, expect your slide to ship in seven to 10 business days.

Compatible Optics stocked by Grayguns:

Be very careful when selecting slide options. Other than the optics listed, Grayguns can not guarantee an optic will fit our slide even if it has the same footprint hole spacing and layout. Design differences – including the amount of thread engagement – may make the sight incompatible with your pistol.

Many parts sold by Grayguns - including but not limited to triggers, trigger kits, internal components and spring kits - are intended for installation by a qualified armorer or gunsmith who is familiar with the firearm.

Although kits fit with no issues in a great majority of pistols, Grayguns cannot guarantee perfect functionality in every instance.

Due to varying tolerances present in all mass-produced firearms, professional fitting by a qualified armorer who is familiar with the pistol's action may be required.

Grayguns offers installation services for all parts kits we offer. If you have any issues or questions about the installation process, STOP IMMEDIATELY and contact the Grayguns Customer Service Team.
