Gun Stories - The Outdoor Channel. It's a great show.
So far, there have been 32 shows in this series. Each one deals solely with one specific firearm, and covers the gamut from military to sporting arms.
It's on the Outdoor Channel at odd times, so you need to set your satellite receiver to record the episodes. I even enjoy most of the advertisements on this show because they are firearm related. Midway sponsors the program but other gun related companies have adds on the program as well.
