Walther PDP 4" & TLR-1 HL IWB Holster

Walther PDP IWB Holster for Streamlight TLR-1 / TLR-1 HL

This inside-the-waistband (IWB) holster is precision-engineered for the Walther PDP pistol paired with a Streamlight TLR-1 or TLR-1 HL weapon light. Designed for consistent retention, comfort, and concealment, this light-bearing holster supports multiple PDP configurations while maintaining a compact, ergonomic profile for everyday carry.

Compatible Walther PDP Configurations

Walther PDP Compact 3.5" with TLR-1 or TLR-1 HL

Walther PDP Compact 4" with TLR-1 or TLR-1 HL

Walther PDP Full Size 4" with TLR-1 or TLR-1 HL

Important: This is a light-bearing holster. Retention is achieved on the weapon light, not the firearm. The holster will not function without the Streamlight TLR-1 or TLR-1 HL installed.

This holster is not compatible with the Streamlight TLR-1 HL-X or TLR-1 HP-X.

The design is indexed around the 1913 rail key, ensuring consistent fit, draw, and retention across supported Walther PDP models.

Construction, Fit & Retention

Each holster is vacuum-formed from a precision-machined mold derived from CAD models of the exact firearm and light combination. All forming, trimming, and finishing processes are completed in-house to maintain tight quality control.

Every holster is function-tested using an actual Walther PDP with a mounted TLR-1–series light to verify secure retention, smooth draw, and repeatable performance.

Retention is fully user-adjustable, allowing you to fine-tune draw resistance. The adjustment system compensates for known dimensional differences between older and newer Streamlight TLR-1 and TLR-1 HL light bodies.

Yes. The holster profile is cut to clear most red dot sights.

Are older and newer TLR-1 lights compatible?

Yes. The adjustable retention system accounts for manufacturing variations between older and newer TLR-1 and TLR-1 HL lights.
