Just some additional info
That "JW" stamp is for Jim Wall. Each craftsman builds a holster start to finish. No assembly line stuff. Jim has been there longer than anyone and is the co-owner of Milt Sparks. I have known Jim for a bit over 30 years now. He has been at the shop that long. His work is exceptional.
They normally have a waiting list of about 4-6 months for a holster. I don't mind, as the holsters will last a lifetime. But when you see one for sale without the wait it is something to consider.
