This Kydex IWB holster for the Sig Sauer P320 is precision-built for the P320 Compact, Carry, M18, and XCompact platforms equipped with a Streamlight TLR-7 X or TLR-7A weapon-mounted light. Purpose-built for concealed carry, this light-bearing holster delivers consistent retention, minimal printing, and all-day comfort — handcrafted in the USA.
This holster retains on the weapon light, not the firearm. A properly mounted Streamlight TLR-7 X or TLR-7A is required for safe and secure use. The holster utilizes the 1913-1 key for optimal compatibility and retention with the P320 Carry rail.
Note: Not compatible with the Spectre slide.
View the official specifications in the Streamlight TLR-7 X data sheet.
We recommend pairing this holster with the Streamlight TLR-7 X USB weapon light for optimal performance and convenience.
Every holster is vacuum-formed over a CAD-designed, precision-machined mold built from the actual firearm and light combination. Each unit is formed, trimmed, and assembled in-house, then function-tested with the real gun and light to confirm retention, draw, and re-holster performance.

Complete your EDC setup with a matching Sig Sauer P320 IWB magazine carrier or P320 OWB magazine carrier.

The holster has excellent retention with a clear, audible click when pressing the gun into it. There are no wedges formed into the side of the holster which is nice as that makes the holster significantly more comfortable than some of my other holsters.
However, I do think a thicker kydex could be used to make the holster a little more rigid. I like the design of this concealment claw, but it's also way too flexible in my opinion. The way it can easily bend backwards away from the belt kind of defeats the purpose of having it in the first place.
Even with my two complaints, I think this is a great holster and will definitely add 4 bros to my list of holster recommendations.
Good holster. Equally good customer service. Would recommend.
The customer service, quality and fast shipping are at the forefront of this industry. I am truly impressed and will continue to be a customer.
I love a holster that fits perfect and just simply does its job. Awesome product for the money. And being left handed they actually had my holster. You’d be surprised how many other companies don’t carry left handed still.
Awesome holster!!!
