Here's one of the wild, inside baseball things about making holsters.
I'm confident that is a Ring's Bluegun in that holster. I have 3 suppliers. None of them list that gun. Went straight to rings, they don't even list any Wilson molds. But one of my suppliers has 2 other Wilson molds from Rings.
It's just nuts sometimes. Some gun companies will have molds made, some will supply guns, some will sell them at a discount to get holsters on the market. Some do none of the above.
And ALL of the companies casting aluminum molds of larger revolvers either quit doing it or went out of business in the last 2 years.
