I regularly carry a S&W 329PD 44 Magnum revolver with a 2.5 inch barrel. I carry it with 200 grain Winchester SilverTip 44 Special rounds. Does this count?
My revolver is the Alaska Backpacker 4 series. Very similar to the Night Guard series. It's stainless steel cylinder is not black, and the sights are adjustable, but otherwise, the same.
I'm sure I'm giving up some velocity with the short barrel, but it sure is convient to carry.
