I normally wear an S&W 642 in a pocket holster along with a full size revolver on my hip. On occassions, I have had to wear a tie, nice shirt, and dress pants (no jacket) to an event. At times like this, especially in hot weather, I have carried my S&W 66 with 4" barrel in my custom pocket holster. With pleated pants and large pockets, it rides comfortably and hides very well. A local holster maker made it for me along with one for an N Frame 4".
