+1, I have been using these for the last several years , best hunting setup you will find. Keeps the gun handy and easy to access yet out of the way of your backpack and is much easier to get to if you are on your ATV or in your vehicle. You can also still use a bow with no problem while wearing these. One of the best hunting/shooting accessories I have bought, worth every penny.
If you want to be economical, you could get an Uncle Mike's shoulder rig. It holds my S&W 500 Mag nicely and you hardly feel its weight, vastly better than hanging off your hip on a belt. Don
Barranti holsters are fantastic! I have two from 7x Leather that are great as well. This is the one I have for my .45 Colt Bisley with 5 1/2-inch barrel.
Barrantileather.com is the only address you need. He makes some lighter rigs for those who don't just sit in a box. Look under his new stuff and you'll see 2 of the newest options.
