FOUR BROTHERS HOLSTERS
Couldn't load pickup availability
This Outside Waistband Light Duty & Competition Kydex holster is designed for the Sig Sauer P365-FUSE equipped with the Streamlight TLR-7 HL-X weapon light using the 1913-3 key. It is also compatible with the Streamlight TLR-7 A and Streamlight TLR-7 X.
Retention is engineered on the mounted weapon light rather than the firearm, providing a secure and repeatable fit. Because retention is light-specific, this holster is designed to function only when a compatible Streamlight weapon light is attached.
Learn more about the compatible weapon lights:
Every Four Brothers Holster is vacuum formed using a precision-machined mold created from CAD models of the actual firearm and weapon light. Each holster is formed, trimmed, folded, and finished in-house before undergoing final fit and function testing with the actual firearm and light combination to verify proper fit, retention, and performance.
Adjustable retention allows you to fine-tune the draw to match your personal preference.
No. Retention is designed around the mounted Streamlight weapon light, so this holster requires a compatible light to function properly.

Havent but the range yet, but the holster fits as expected. Great quality. Will buy again.
The holster is made very well. Solid retention, no sharp edges, and the mounting was flawless. I appreciated that they mounted the True North Concepts mount to the holster just to save me a little time. I
And the shipping was quick!
Fits like a glove
Fits like a glove with good retention. Love it
Just unboxed and test fit. All the screws were already tight and all components feel quality. The kydex is thick and sturdy. Would buy again and plan on buying other products from this company.
