This IWB holster for the Sig Sauer P365-FUSE & FOXTROT2R is engineered for secure and comfortable Inside Waistband concealed carry. Designed for everyday carry, this holster provides consistent retention, reduced printing, and a streamlined profile for all-day comfort.
This holster is engineered specifically for use with the Sig Sauer FOXTROT2R weapon-mounted light. Retention is achieved on the light, not the firearm, and the holster will not function without the light installed.
The holster retention is on the light itself, not the pistol, which means this holster will not work without the light mounted on the firearm.
Information about the Sig Sauer FOXTROT2R weapon-mounted light can be found HERE
Each holster is vacuum-formed using a precision CAD-based mold built from the Sig Sauer P365- with the FOXTROT2R light. Every holster is formed, trimmed, and assembled in-house, then tested with the real firearm and light combination to ensure consistent retention and reliability.
Understanding your carry configuration is critical. Learn more in our holster belt attachments and carry position guide.
We have a kit available should you need to remove the modwing that includes (2) 3/8" Screws, (2) 1/4" Rubber Spacers, and (2) 1/4" Threaded Posts which can be purchased HERE.

Seriously, I outfitted this Sig Fuse with an optic and a light and was worried about a proper IWB holster becoming an expensive mission. Got to hand it to you guys. You got it right. I have to look no further.
Only a handful of folks make a holster for the Sig Fuse with a Foxtrot weapon light. And you guys nailed it. Holds tight and just a few screw twists dials in the perfect amount of retention. I was concerned from the look about the high sweat guard, but happily it is actually just the right height. The Monoblock clip is a bit of a PITA to attach, but in a good way - this thing will not fall off. And unlike many holster wings, this one is placed in the exact correct location to truly do as intended. So you guys passed your geometry class I guess!
Very happy with my purchase.
This holster is a perfect fit for the Sig Sauer P365-FUSE with the FOXTROT2R light. It holds securely, draws smoothly, and is comfortable enough for all-day wear. Highly recommended!
The claw needs to be a little higher to match the top inside of the belt clip. Other than that it’s great quality.
Great fit and comfortable
Awesome holster and perfect fit. Easy draw yet good retention. Couldn’t be happier!!
