I use the same exact Don Hume for my full size (its my EDC) and I love it. Occasionally (when I'm out in the woods usually) I use a Blackhawk Serpa holster. I can conceal in the right T Shirt, BUT it is easier and much more comfortable wearing a light weight cotton or under armor shirt as an under shirt with a decent button up shirt over top. I have a few from Eddie Bauer, Columbia, Under Armour and Dickies. Depending on your build, you will want your over shirt to be one size larger.
