This holster is very similar to my OWB leather holsters from "Blackhills" leather. I think the mod# of mine is BH 21 P. I have 3 of them, each for a different pistol. All mine are left handed though, and clearanced as necessary for my RDS.
If you're like Night Rider and I and have a few years on us that makes the IWB holsters not as comfortable as 'used to be', then look into "Blackhills" leather and ask for Rudy. He'll do you right and at the right price.
Full disclosure: I have absolutely no financial interest in "Blackhills" leather, directly nor indirectly. I just appreciate good quality and value when I see it.
