This holster deserves its own thread.
This is an extremely minimalist approach to aiwb. With its limited wedge and yaw pad, I think it is functionally similar to the George, but to me more comfortable because it's leather.
As shipped the ride height is pretty extreme. I have a half inch of clearance to my knuckles. This results in some butt print. This is fine in Texas, but Jim is making me some extra wedgy bits for the refined sensitivity of Kansas City. The ride height makes it very comfortable in the muzzle area.
I find myself centering it more than anticipated because of the printing.
Retention is good, but unlike other jrc holsters (I guess I've bought about seven?) it did not require break in.
The thumb safety is not forced on by insertion in the holster, and will push the Guard aside, but the safety cannot be disengaged while holstered. The mag release is easy to hit on purpose, which I prefer.
It is inherently a fast holster. I have to slow down enough to sweep onto the butt rather than just slamming my and down so I don't get caught on top of the tang; and it's still fast.

I will be ordering one shortly for a commander. I will probably seek to drop the ride height by 1/4", seek some negative cant, and see if we can get a little more defined on the safety.
