Important: This holster is light-bearing and retains on the weapon light, not the firearm itself. The holster will not function without the light installed.
This holster is not compatible with the Streamlight TLR-1 HL-X or TLR-1 HP-X.
The holster is designed around the 1913 rail key to ensure consistent fit and retention across supported models.
Construction & Fit
Each holster is vacuum-formed using a precision-machined mold created from a CAD model of the actual firearm and light combination. All holsters are formed, trimmed, and finished in-house.
Final fit and function testing is performed using the actual pistol and mounted light to ensure proper retention, smooth draw, and consistent performance.
Retention is user-adjustable, allowing you to fine-tune the draw resistance to your preference. The adjustment system accounts for known variations in TLR-1 and TLR-1 HL light bodies, ensuring compatibility with both older and newer production lights.

Frequently Asked Questions
Will this holster work without a weapon light installed?
No. Retention is achieved on the Streamlight TLR-1, TLR-1 HL or TLR-1 HP itself. The holster will not retain the firearm safely without the light mounted.
Does this holster support red dot optics?
Yes. The holster profile is cut to allow clearance for most red dot sights.
Are older and newer TLR-1 lights compatible?
Yes. The retention adjustment system is designed to accommodate manufacturing variations between older and newer TLR-1 and TLR-1 HL or TLR-1 HP lights.
What should I do to prevent hardware from loosening?
We strongly recommend applying a removable thread locker to all holster screws after setup to prevent fasteners from loosening during use.
