Description

Inside-Waistband (IWB) Holster for Glock 19 / 19X / 45 Gen 5 & Glock 19 / 23 Gen 3–4 — Streamlight TLR-1 HL

Precision vacuum-formed IWB holster engineered to fit Glock 19, 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 3/4 variant). Retention is on the light body, not the slide; the holster will not retain correctly without the TLR-1 HL mounted.

Compatibility & Fit Notes

  • Primary fit: Glock 19, 19X, and 45 Gen 5 with Streamlight TLR-1 HL.
  • Gen 3/4 variant: Select the Gen 3/4 holster for Glock 19 & 23 Gen 3 or 4 with TLR-1 HL compatibility.
  • Not compatible: Glock 23 Gen 5 with TLR-1 / TLR-1 HL.
  • Fit tolerance: Minor variations between older and newer TLR-1 / TLR-1 HL housings can affect fit; the retention adjustment is engineered to accommodate these tolerances.

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.

Product Details & Manufacturing

  • Vacuum-formed from a CAD-designed, precision-machined mold based on the actual firearm for repeatable, accurate fit.
  • Formed, trimmed, folded and quality-tested in-house; each holster is tested with the pistol + light to confirm retention and clearance.
  • Made from durable .093" thermoplastic for strength and consistent performance.
  • High sweat guard standard with minimal material and smooth edges for comfortable IWB carry.
  • Profile cut to accommodate most red dot sights and optics.
  • Optional Modwing available to reduce printing (two insert positions to adjust leverage against the belt).
  • Proudly made in the USA.

Key Features

  • Light-based retention (requires Streamlight TLR-1 HL).
  • Adjustable retention hardware for personalized draw tension.
  • High sweat guard for slide and optic protection.
  • Optics-ready profile cut for most red dot sights.
  • Optional Modwing for print reduction.

Care & Maintenance

We recommend applying a removable thread locker to each holster screw after installation to help prevent lost hardware during regular use.

FAQ

Will this holster work without the Streamlight TLR-1 HL attached?
No. Retention is on the light body; remove the TLR-1 HL and the holster will not retain the firearm correctly.
Does this holster clear red dot optics?
The holster profile is cut to accommodate most red dot sights and optics used on compact and mid-size Glock slides.
Can I adjust retention?
Yes — retention tension is adjustable to set draw resistance for carry or competition needs.
What is the Modwing and why use it?
The optional Modwing includes two inserts that change how the holster leverages against the inside of the belt to reduce printing. It’s useful for concealed carry where minimizing outline is a priority.
