Hey Joe
I found Wes Daems in Montana to make my holster. This guy is an avid hunter and makes his living by hand-building holsters and other leather work. You will deal only with the owner, builder (Wes) when dealing with his company. The only time I get someone else (Wes's wife) is when Wes is hunting!
Go to his site and click on "Chest Holster".

One of us always carries our Redhawk for safety, on our hog hunts down here in wicked-thick country. This holster has no real competition in my opinion for cost and functional performance. And, the fact that you are dealing with a fine man, a serious hunter and, a leather craftsman of great skill makes it a win-win-win situation.
I have never met Wes. I get no compensation of any kind from Wes or his company.
