Love these new chest rigs from GunfightersINC. They remind me of the ones the old tankers and fighter pilots used to wear but instead of leather these are made of Kydex.
The straps are more radio harness like so everything looks like it stays close and handy where it belongs with no flopping around. The gun is right where you can get to it, even when wearing a pack. Well done.
