Ruger MK shoulder holster.

Who makes a good vertical shoulder holster for Ruger Mark series pistols ? I made one from a nylon shoulder holster made for a revolver by replacing the holster that didn't fit the gun right with a Uncle Mike's nylon belt holster. It works good, but I would like to have pro made one. There was some cutting and hand sewing involved. It carries well, but the holster I cut down was originally made for a Ruger MK2 with a 10 inch barrel.

I have carried my MKII with a 10 " barrel in a Bianchi X15 large for well over 20 years.
It works great.
I would assume a smaller size would fit a shorter barrel.
