A man who uses a Smith gun is typically someone to whom women are attracted, dogs listen to, and always need to find people to take their excess of game birds. Parker men are simply unfortunate souls who never were able to step up to the best. Fox shooters plainly wish they were allowed to carry the guns of their Parker and Smith shooting friends as they make their way around the course. (And they all pray to their Maker each night their thanks that they aren't saddled with Winchesters, Lefevers, Merkels, Purdeys, Hollands,
et al.)
Truth: they're all good and represent quality and workmanship rarely found in this world anymore. (Except the Smith might be a shade better.) Close your eyes and pick one. Literally. Heft similar models side-by-side and see which one speaks to you. Gun fit, condition, and balance that suits you is more important than which brand you seek out. Swing on a few targets with each choice (if allowed) and take it from there. Just bear in mind that Smith guns gain you a few extra brownie points when seeking admission at the Pearly Gates.
