Nothing wrong with the 659 for carry use. What are your parameters for use? I make holsters for concealed carry for many people. The main thing that I need to know is what do you expect the holster to do for you. Next, I need to know about your physical profile (height, weight, etc) and how you intend to dress when carrying.
Glad to advise you if you wish. As usual, my advice is free and worth every penny of the cost!
