Trail Gun, for the purpose of this post, is one you would carry on an outing where shooting it is not planned; except for a "necessity" ...ie you are not out hunting or plinking.

One of mine is this S&W Air Lite PD .44 magnum, tucked up high on a regular belt in a Galco Phoenix holster, loaded with 3 240 grain light loads and 3 320 grain SSK hardcast full-house loads.
