Inside-Waistband (IWB) Taco Holster — Glock 17 & 47 Gen 5 and Glock 17 & 22 Gen 3–4 with Streamlight TLR-1 HL
Precision-engineered IWB taco-style holster designed to fit Glock 17 Gen 5, Gen 6 & Gen V and 47 Gen 5 pistols, as well as Glock 17 and 22 Gen 3–4, when equipped with the Streamlight TLR-1 HL or TLR-1 HP weapon-mounted light. Retention is based on the light body, meaning the holster will not function correctly without the TLR-1 HL attached.
This holster will not work with the TLR-1 HL-X or TLR-1 HP-X light.

Retention & Performance
This holster uses light-based retention — the weapon light, not the slide, provides the locking point. It will not retain the firearm correctly without the TLR-1 HL or TLR-1 HP installed. Retention can be easily adjusted to achieve your preferred draw tension for concealed carry or training use.
Product Details & Construction
- Vacuum-formed using a precision-machined mold developed from a CAD model of the actual firearm for repeatable accuracy.
- Formed, trimmed, folded, and tested in-house using the correct pistol/light setup for verified retention and fit.
- Made from durable .093" thermoplastic for long-term structural strength.
- Profile cut to clear most red dot optics and tall sights.
- High sweat guard protects slide and prevents irritation during carry.
- Optional Modwing (two insert options) helps reduce printing by adjusting leverage against the belt.
- Lightweight, minimal design with smooth edges for comfortable IWB carry.
- Proudly made in the USA.
