P320 Full Size Black IWB Kydex Holster - Adjustable Ride & Cant

Our review of this P320 Full Size Black IWB Kydex holster finds it best suited for owners of the Sig Sauer P320 Full Size 9MM/.40SW with manual safety or the P320-M17 equipped with a Streamlight TLR-8/8A and RDS who want a low-profile, adjustable inside-the-waistband carry option. The single biggest reason to buy is its tailored fit and modular adjustability: ride height, cant and retention can be dialed in for appendix, strong side, behind the hip or cross carry, delivering a secure but concealable setup for daily carry.

Key Features

• Model specific fit: Molded specifically for the Sig Sauer P320 Full Size 9MM/.40SW Manual Safety and P320-M17 with Streamlight TLR-8/8A and RDS to provide a close, consistent lockup for quick access.
• Adjustable ride and cant: The clip can be unscrewed and repositioned to change height and tilt so users can fine tune draw angle and concealment for appendix, strong side, behind the hip or cross carry.
• Durable Kydex construction: Built from.08-in Kydex that resists water and rot and holds its rigid shape for long-term retention and re-holstering consistency.
• Lightweight and low profile: Designed for inside-waistband wear with a belt and an untucked shirt to minimize printing and reduce pressure during extended carry.
• Washable and low maintenance: Waterproof Kydex makes cleaning simple and eliminates concerns about leather degradation from sweat or moisture.

Who It's For

This holster is aimed at owners of the Sig P320 Full Size 9MM/.40SW Manual Safety or P320-M17 who carry with a Streamlight TLR-8/8A and want a molded Kydex IWB solution that can be tailored for position and draw angle. It fits users who prioritize a form-fitting, easy-to-clean holster that keeps the pistol secured while allowing quick access.

Those who should look elsewhere include shooters who need ambidextrous mounting hardware out of the box or users who prefer outside-the-waistband concealment or leather for a different carry feel; the design is purpose-built for IWB use with a belt and an untucked shirt for concealment.
