Another vote for RLN holsters (buy it from forum sponsor Automatic Accuracy)
I've used the BT DOH, a lot. It works, and everyone you buy is exactly the same.
2 things I dont like about it:
The DOH hanger is a weird shape and gets in the way. I know people who run this holster with customized hangers for this reason.
The holster is a 3 piece unit held together by more than a dozen itty bitty pieces of hardware...if you buy one, disassemble it, use lots of loctite, and keep spares handy.
Also, the BT usually needs shims installed to get the gun into a rules-compliant position. It tilts way too far out on most people.
The stingray attachment has these stupid belt shims that fall out (I've found a bunch of them on the ground at ranges like ussa)
You'll need some zip-ties to keep that thing solid and in place...or use their teklock attachment.
The RLN holster is solid, one piece of kydex. I swapped out the hardware for some adjustable knobs, but I'm picky that way...
