⚠️ Holsters made to support Align Tactical®, Gas Pedal®, and Tactical Development aftermarket accessories are non-returnable except for quality or workmanship issues, as these items affect concealability and fit.

Light Compatibility

Retention is based on the Streamlight TLR-1 HL-X or HL-X USB light body, not the pistol itself. This holster will not work without the weapon light attached. The holster is designed for use with the 1913 key.

⚠️ Not compatible with the Streamlight TLR-1 or TLR-1 HL models.

For more details, see the Streamlight TLR-1 HL-X product page. Our recommended option is the Streamlight TLR-1 HL-X USB available from Four Brothers.
