I saw this post here for awhile so I thought I would chime in. There is a couple custom compnaies that will help, they might require you to send them your gun. I use a galco explorer made for a glock 22 to carry my mk2 4 in. It works great and is not boned to the gun but is made for specific models. I realized this would work when I found out my mk2 road well in a bianchi millitary style flap holster.
