The first holster is the SOB-5. It is actually worn at 5 o'clock (7 in this case, as it's a lefty) Not over the spine. When i mold this, the butt of the gun is torqued inwards, so it doesn't protrude. This is for a Springfield Centurion, which is why the blue gun protrudes a bit.
The last is the BS-SSC. It is left handed version of a cross draw rig, designed to be worn at 5 o'clock also. This one hides a revolver really well.
Both are Horsehide with burgundy and cordovan finishes. All hand sewn.
I know a lot of folks bemoan this style of carry, but the customers like them and it takes no more practice than other modes of carry to draw from properly.
