Thanks for the comments, everyone. For the iwb i just used a screw through the base of the snap screwed to a t-nut on the back of the holster. I might sandwich the t-nut between the leather of the holster for the next one, although I'm not sure it would be as strong of a connection that way. The t-nut on the outside isn't that appealing cosmetically.... I haven't use Angelus dye yet but I would like to, especially for browns. The Angelus finish has worked well. I really enjoy working with the Wickett & Craig leather, it has molded much easier than the Tandy leather I first started with. It holds the molding nicely. Boomstick- thanks for the advice. I will definitely pull the rear slot/loop in on the next holsters I do. I admire your work. Again, thanks everyone for the comments and advice.
Here is another holster I've made for a Kahr.
