What kind of holster are you looking for? A buddy of mine makes custom holsters. He usually gets requests for either IWB or pancake models. As long as he has a gun mold he can make a holster for it. If you're interested in him making you one then I'll let him use my AMT .45 as a mold.
I haven't had him make an IWB for me but he's made 2 pancakes and a shoulder rig. His IWB are the usual thin leather with metal clip style. I don't know what he charges now for pancakes but last summer he made a couple for other guys on another list and it was about $35 for basketweave. Colors are black, mahogony, brown, and tan.
Here are the ones he's made for me. The Glock holster is mahogony and the S&W 63 is brown. He uses very heavy leather. The Glock holster has been carried a lot when I was in plain clothes and off duty even tho it doesn't show any wear and is still stiff. The S&W 63 holster has been carried a lot when hunting. He doesn't bone the leather to the gun but with the thumb break the gun isn't going anywhere.
If you're interested drop me a PM and I'll send you his name and telephone.
