I bought a MacDaniel II from Andrews Custom Leather
http://www.andrewsleather.com for my Colt Commander a while back, and recently had the opportunity to spend 4 days training with it. I probably drew and re-holstered 500+ times over 4 days, and I wore it for about 16 hours per day.
I have to say that I am very very impressed both with the design as well as the quality. Other than some scuffing of the inside leather from the very sharp edges on my Colt, the holster looks brand new. It is very concealable, and very comfortable.
There were many times that I forgot I had it on. A number of people in my class had positive comments and questions about the holster, and at least one guy was planning to order one for his Springfield GI.
Thanks to Sam for making a great product, and having the personality and customer service to go along with it.
