FOUR BROTHERS HOLSTERS
Couldn't load pickup availability
Inside Waistband Holster designed to fit the Sig Sauer P365-FUSE handgun with the Streamlight 1913 version of the TLR-7 Sub light mounted to the pistol.
The holster is confirmed to fit the P365-FUSE slide on the Mischief Machine Alpha Gen 3 grip module with the 1913 TLR-7 Sub weapon-mounted light.
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.
This holster is designed to function with the #1 key.
For this holster to fit correctly, you will need the Streamlight TLR-7 Sub or TLR-7 X Sub 1913 version (part# 69402) or TLR-7 HL-X Sub (part# 69505) mounted to the pistol.
Information for the Streamlight TLR-7 X Sub can be found here.
Information for the Streamlight TLR-7 HL-X Sub can be found here.
Our preferred light option for this holster is the Streamlight TLR-7 HL-X Sub USB, which can be purchased from us HERE.
This holster will NOT work with the SIG version of the TLR-7 Sub.
Our holsters are vacuum-formed with a precision-machined mold designed from a CAD model of the actual firearm and light.
Each holster is formed, trimmed, and folded in-house. Final fit and function tests are done with the actual pistol and light to ensure the holster fits the gun/light combination and has the correct amount of retention.
The holster's retention is easily adjusted so that the fit can be set to your personal preference.

I’ll be frank I’m less than impressed with what I received the plastic was bending at the slightest bit of pressure and felt very cheap. Would not recommend this for anything duty or hard use after a single trip to the range it was in the trash. Will not be purchasing holsters from here again T-Rex/safari land are only slightly more expensive and the feel and rigidity of the plastic blows this out of the water.
Liam,
This is Jason. Could you provide a bit more detail on where the hoster had issues and what happened to the monoblock? This is not what we typically hear, so I'd like to get more information from you so we can improve our products.
Hands down the most comfortable holster ive owned. Customer service was extremely quick, replying over the weekend aswell! Found my new go to holster
The holster absolutely exceeded my expectations. It fits my Fuse and Tlr7x sub perfectly. There doesn't seem to be any hotspots of any kind. Very easy to draw from, but offers great retention.
Fits well, comfortable
Fits perfectly!
I had a hard time finding an IWB holster for my gen 2 Sig P365 AXG Legion. 4 Bros came through with a great fitting, quality product. This is my first 4Bros holster and I am very impressed.
Amazing!!!!
Great holster! I manage to heat up one side a little in order to fit in my antimatter gas pedal. Still fits like a glove! Love it
Absolutely love this holster for my Hellcat!!!
