Inside-Waistband (IWB) Holster for Glock 19 Gen 5 or Gen V, Glock 19X / 45 Gen 5 & Glock 19 / 23 Gen 3–4 — Streamlight TLR-1 HL
Precision vacuum-formed IWB holster engineered to fit Glock 19 Gen 5, Gen 6 or Gen V, Glock 19X, and 45 Gen 5 pistols with the Streamlight TLR-1 HL weapon light — also available for Glock 19 & 23 Gen 3–4 (select the Gen 3/Gen 4 variant). Retention is on the light body, not the slide; the holster will not retain correctly without the TLR-1 HL mounted.

-
Not compatible: Glock 23 Gen 5 with TLR-1 / TLR-1 HL.

How Retention Works
This holster uses light-based retention—the retention point secures the light housing, not the pistol slide. Retention tension is adjustable so you can set draw resistance to your preference. Remove the TLR-1 HL and the holster will not function as intended.
