I have a S&W Model 12-3 K frame airweight square butt and 2 inch barrel that I have been carrying concealed daily. It is a joy to carry because it is so light but big enough to shoot well. I use a Theis IWB holster that works very well. Any of you guys carry one of these awesome guns? I like it so much that I am keeping my eye out for another one to use for my bug.
