IWB Kydex Holster for Sig P320 Full Size - Adjustable Concealment

In this review of the IWB Kydex holster for the Sig Sauer P320 Full Size with Streamlight TLR-7/7A, the bottom line is simple: this is a practical, adjustable inside-waistband carry option for shooters who prioritize concealment and a durable, low-maintenance material. The single biggest reason to buy is the holster's combination of rigid.08-in Kydex construction and multiple adjustment points that let the user dial in ride height, cant and retention for reliable everyday carry. It is built in the USA and backed by a lifetime warranty, which reinforces its intended role as a long-term carry solution.

Key Features

• Form-Fit Design: Specifically molded for the Sig Sauer P320 Full Size 9MM/.40SW with manual safety and a Streamlight TLR-7/7A, providing a secure, tailored fit for that configuration.
• Adjustable Ride and Cant: Detachable clip and mounting positions let the wearer change height and angle quickly to suit appendix, strong side, behind-the-hip or cross carry.
• Retention Control: Adjustable tension hardware provides a customizable draw force so the pistol stays in place during movement while remaining accessible.
• Durable Kydex Build:.08-in thick Kydex is waterproof, washable and resistant to warping or rot, giving long-term structural integrity versus softer materials.
• Comfort-Focused Shape: Lightweight, thin profile designed for inside-waistband carry with an un-tucked shirt to reduce printing and pressure on sensitive areas.
• Lifetime Warranty: Made in the USA and backed with a lifetime warranty, offering long-term confidence in workmanship and materials.

Who It's For

This holster is best for owners of the Sig Sauer P320 Full Size who run a manual-safety model with the Streamlight TLR-7/7A and want a dependable inside-waistband option that can be finely adjusted for carry position and retention. It suits daily carriers who favor a rigid, low-maintenance material and who dress with an un-tucked shirt or need a holster that tucks inside the waistband for better concealment.

It is less appropriate for shooters who need a hybrid leather setup, ride outside the waistband, or carry without a belt. Also, those who prefer passive retention systems built into the pistol holster rather than adjustable screw tension may want to compare other styles.
