I've used two of their "Master" pancakes (for a Smith 4516 and a SIG 220), as well as their single and double mag pouches. They are made by an outside contractor (never knew the name) but Dillons' guarantee is simple (don't like it - we will replace or refund as you wish). The quality is very good, and they could easily sell for more. The molded fit is very well done, and the stitching is precise and strong. The spring retainer in the mag pouches takes a little breaking in, and will mark blue mags, but once settled in are very secure without binding. All in all, lots of bang for the buck with this line.
If they offered more for revolvers, or even more barrel lengths in the revolver rigs no in the line, I'd have quite a few more in my holster drawer
