Strangely enough - and perhaps only here in the land of "Second Amendment" fervor, there are a number of sportsman shows going on regularly. (It actually very common right now in my part of the nation because whitetail deer season will soon be upon us.) These shows are popular, geared primarily toward hunters and fishermen, they also cater to memorabilia collectors...and the money flows. Someone who was willing to specialize in these sorts of "pens" (and I think "pens" is a stretch) would probably make a mint. I can't bring myself to even try a pen like the ones Terry pointed out, or even the less ostentatious rifle pens, but Phil spoke volumes; someone is buying these. It just is not me!
