Great question. After additional conversations, the local option was simply to see if there were individuals he could support nearby, however, given his previous experience, he would rather get a good quality holster above all else. Though he is particular to leather. Any concerns I should share with him in regards to whether leather would or would not be good option?
Nothing wrong with leather for a holster, provided the holster-maker knows what they are doing. Milt Sparks holsters, for example, are excellent. Some other folks, not so much. (Just like kydex--some holster-makers know what they are doing, and others are people with a sheet of kydex and a heat gun who give you a blank look when you ask how they finished the edges.)
I personally go with kydex because I want my holster to act the same whether it is hot or cold or wet or dry, and kydex holsters are easier to clean and take care of, while still being cheaper than leather for a quality one. That being said, thousands of people who actually carry and shoot a lot still like leather, so it isn't a poor choice as long as it is a quality holster. And there's no doubt that a good leather holster looks better than a kydex one, and for some people that's important. (I've never understood that---I want my gear to look boring and unobtrusive, and not attract a second look at all, but some people really want their gear to look good, and that's fine.)
I'm blanking on other good leather holster makers at the moment who have a track record of quality (though I'll probably remember right after I post this).
http://www.miltsparks.com/products-55-bn.phphttp://www.miltsparks.com/products-i-bak.phpAh yes, Mitch Rosen holsters also have a solid track record of quality.
http://mitchrosen.com/products/holsters/belt-holsters/Man, there is a newer holster maker that several people who shoot a lot like, but I'm blanking on the company name. If I remember, I'll come back and edit this.
If your friend wants something with active retention at all for OWB carry (is he ever planning on open carry?) then the Safariland ALS is
by far the best holster out there, in my opinion. That's a separate discussion, though.
