The Kenai Chest Holster for Glock from Gunfighters Inc., is very well made, and it is heavy duty with great adjustability. It does not have tension adjustment on the Kydex holster so it can be sticky on the draw. I suggest adjusting the harness so that it fits very snug. Otherwise, when you go to draw in a pinch (say when a griz is closing in), the whole harness will pull around your body and the firearm won't release. I run it under a Kuiu Pro Bino Harness, and I really like the system. Overall it's a great product and I recommend it. As with any harness, make sure you practice your draw cycle and develop the muscle memory to use your firearm when it counts.
