Glock 19/17 with TLR-8A OWB Holster

Glock OWB Light-Bearing Holster – Streamlight TLR-8 Series

This Outside-the-Waistband (OWB) light-bearing holster is designed to fit select Glock full-size and carry pistols equipped with a Streamlight TLR-8–series weapon-mounted light. It provides secure, light-based retention and a consistent draw for range use, training, and OWB carry.

Important: Retention is achieved on the weapon-mounted light rather than the firearm itself. This holster will not function properly without a compatible Streamlight TLR-8 light installed.

Construction & Fit

Each holster is vacuum-formed using a precision-machined mold developed from a CAD model of the actual firearm and supported Streamlight light. All forming, trimming, and folding is completed in-house for consistent quality and performance.

Final fit and function testing is performed using the actual pistol and light combination to ensure proper retention, smooth draw, and reliable performance. Retention is fully adjustable, allowing you to fine-tune draw resistance to your preference.
