I've got one and I think it's on par with a Milt Sparks Summer Special except that the Wilson has the extended flap for the safety and it's just a tad bit thicker than the Milt Sparks. The Wilson only offers one size belt loop so it will fit loosely an belts less than 1 3/4" wide. I wear a 1 1/2" belt and I don't have a problem with it shifting.
I believe most of Wilson Combat's holsters are designed by Bill Wilson and produced by Rafter S Gunleather at www.raftersgunleather.com. Rafter's stuff looks really nice and the prices for exotic leathers are the lowest I've seen.
