Very happy with this super lightweight, no-frills chest rig from Razco. I'm using it with a custom Glock 20 (10mm), with a threaded barrel, a Streamlight TLR7a weapon light and a Trijicon 3.25 MOA RMR Type 2 LED sight.
The holster is light and thin enough that I typically wear it under my bino bivvy when hunting or scouting. Then, I can drop the binos while back at camp, but stay strapped with the pistol.
The straps are easy to adjust and again, this rig weighs almost nothing.
When ordering, make sure you specify the correct pistol, details like a weapon light, RMR, or threaded barrel and so on to ensure the optimal fit.
Overall, I highly recommend the Razco Chest Rig!
