Description
Glock 19 & Glock 45 IWB Holster – Streamlight TLR-8 Series
This inside-the-waistband (IWB) holster is designed to fit the Glock 19 Gen 5 and Gen V, Glock 45, and Glock 19X when equipped with a compatible Streamlight TLR-8 series weapon-mounted light. It is optimized for concealed carry, providing consistent light-based retention, adjustable fit, and a slim profile to reduce printing.
Important: Retention is achieved on the weapon light itself, not the pistol. This holster will not function properly without a compatible TLR-8 series light mounted to the firearm.
Compatible Firearms
- Glock 19 Gen 5 & Gen V
- Glock 45 (Gen 5)
- Glock 19X
Required Weapon Light Compatibility
To ensure proper fit and function, this holster requires one of the following Streamlight TLR-8 models:
- Streamlight TLR-8A (old) or TLR-8X – Part #69414
- Streamlight TLR-8A G (old) or TLR-8X G – Part #69434
Precision Construction & Fit
Each holster is vacuum-formed using a precision-machined mold created from a CAD model of the actual firearm and light combination. All forming, trimming, and folding is completed in-house for consistent quality and repeatable fit.
Final fit and function testing is performed using the actual pistol and light to ensure proper retention, smooth draw, and reliable performance.
Retention is user-adjustable, allowing you to fine-tune draw resistance to match your personal carry preference.

Fits perfectly.
I have been using the holster now all day for a week. It is working very well. I find it more comfortable to wear than my other holsters. With my other holsters I get uncomfortable and tend to not carry. This one seems to integrate perfectly with my body type and clothing. I can easily wear it when I am driving or lounging around the house. It has broken in somewhat now and the 17 fits better. I plan on purchasing another one for my son who is applying for CCW. It would be nice to have color options. I might paint mine to give it a little flair. Thanks Jason
I purchased the holster for concealed carry of my gen 3 Glock 19 and 17 with TLR8 light. I am new to the CCW world, this is only my second holster purchase. I have been wanting to carry with a light in place as I am often out after dark. This was the only holster I could find that accommodated the TLR8. It is visually appealing and is easy to use. I can tell it is a bit bulkier than my other holster. It is harder to conceal than the holster without a light. Of course, this is to be expected. I had some issues with retention when it first arrived. There was no retention and the gun would easily fall out. I reached out to the owner Jason who responded immediately and we did some videos and chatting. All I had to do was torque the retention screws. Now it has adequate retention but is still easy to draw. The holster is marketed as a G19 and G17 holster. Both guns will work but the G19 just seems to fit a lot better. I plan on only using it for the 19 anyway. The holster is recommended and the customer service is exceptional
