GRITR OWB Kydex Sig Sauer P320 Holster - Optic Ready, Adjustable Cant

In this review of the GRITR OWB Kydex holster for the Sig Sauer P320 family, the bottom line is straightforward: it is a sturdy, optics-ready outside-the-waistband holster for shooters who value modular carry and secure retention. The reviewer finds it best for owners of P320 variants who run red dot optics or compensators and need a holster that adapts to different setups. Construction from 0.08' in Kydex and compatibility with Safariland QLS and G-Code RTI systems make it a practical choice for range use, everyday carry with a belt-mounted platform, or quick transitions between rigs.

Key Features

• Optics-ready design: The optic cut and open bottom accept many red dot sights and compensators so the holster works with common pistol customizations.
• Model fit: Built specifically for a wide range of Sig Sauer P320 variants, ensuring precise contact points for those guns listed by the manufacturer.
• Retention adjustability: An adjustable retention screw lets users tune draw resistance to their preference for a balance of speed and security.
• Cant versatility: The adjustable cant permits carry at many angles up to 360 degrees, accommodating different draw styles and mounting systems.
• Attachment compatibility: Fits Safariland QLS and G-Code RTI interfaces so the holster can be moved between compatible belt mounts and platforms.
• Durable material: Made from 0.08' in Kydex that is lightweight, waterproof, and easy to clean for long-term field use.

Who It's For

The GRITR OWB holster is aimed at P320 owners who use or plan to use red dot optics and want an OWB platform that will accept compensators and different slide configurations. It suits range regulars, USPSA/IDPA hobbyists who prefer belt-mounted rigs, and concealed carriers who use robust OWB setups for comfort and retention.

It may not be the best choice for users looking for a soft-case, minimalist inside-the-waistband setup, or those who need a fully universal holster for many pistol brands. Also, buyers who require an ultra-loose draw out of the box should expect to adjust retention to their taste and possibly break in a very snug fit.
