Firearm Compatibility
Compatible Firearm:
IMPORTANT: This holster does NOT fit the SIG Sauer P320-XTEN-COMP.
Compatible Streamlight Weapon Lights:
- Streamlight TLR-1
- Streamlight TLR-1 HL
- Streamlight TLR-1 HP
NOT Compatible with TLR-1 HL-X or HP-X
Important Fitment Requirement: This holster is designed around the P320 key rail insert used with compatible Streamlight TLR-1, TLR-1 HL, and TLR-1 HP lights.
Some variations in the light body between older and newer TLR-1 models can affect fit and retention. Our adjustable retention system is designed to accommodate these manufacturing tolerances across compatible generations.
Light-Based Retention: This holster retains the firearm through the mounted weapon light rather than the pistol frame. The compatible light must remain installed for proper fit and retention.
Engineered for a Precise Fit
Each holster is shaped around a precision-machined mold created from a CAD model of the actual firearm, providing consistent dimensions and reliable retention around the designated firearm and light combination.
Our manufacturing process includes vacuum-forming, trimming, assembly, and hand-finishing, all completed in-house. Every holster is individually checked with the actual pistol and mounted light to verify proper fit, retention, and draw performance.
The adjustable passive retention system allows shooters to customize draw resistance while accommodating minor dimensional differences between compatible TLR-1 light models.
