Key Features & Benefits
Perfect Fit for Sig P365 XL – Laser CAD-designed specifically around the Sig Sauer P365 XL for a precise fit, smoother draw, and reduced wear on your slide and controls. OpticsPlanet

Concealment-Ready Appendix Holster – Slim profile, minimal bulk, and a tucked-in design that disappears under light cover garments while keeping the grip where you need it for a fast, repeatable draw. OpticsPlanet+1
Adjustable Cant (0–15°) – Fine-tune your holster angle from straight drop to forward cant to optimize concealment, comfort, and draw ergonomics for your body type and carry position. OpticsPlanet
Secure 1.5" Belt Clip – Robust polymer belt clip locks onto standard 1.5" carry belts, keeping the holster anchored during movement and when you draw. OpticsPlanet+1
Audible Passive Retention – Built-in passive retention system provides a positive “click” when the pistol is fully seated, so you know your P365 XL is locked in place. OpticsPlanet
RMR-Ready Slide Clearance – Sculpted around an optics-ready slide with an RMR-style footprint, so you can run a red dot on your P365 XL without interference from the holster body. OpticsPlanet
Tall Sight Channel & Open Muzzle – Tall sight channel accommodates higher-profile/tritium or suppressor-height sights, while the open muzzle design plays nicely with threaded barrels and compensators. OpticsPlanet
Abbreviated Sweat Guard – Smartly contoured sweat guard keeps sharp slide edges off your skin without adding unnecessary bulk around the grip. OpticsPlanet
Durable .08" Boltaron Construction – Tougher and more temperature-stable than standard Kydex in many conditions, Boltaron provides long-term durability for daily carry. OpticsPlanet+1
