I was pleased with the leather work Don at Cross Bar S Leather did for me. He does knife leather as well.

Be careful...those waters run deep! My vote for best "production" mfg would be Dan Wesson. There are cheaper options, but Wesson sits in a sweet spot of value for the dollar.
Very pleased with the quality of the holster and belt Don made for me. Communication was excellent, with a double check on belt length before construction. Emailed pictures of the holster asking if this was suitable. All in all a very nice setup from a stand up guy. Thanks Don.
Another awesome personality bites the dust. That was back in the days when talent didn't feel the need for political commentary to entertain. They enjoyed life! RIP.
