Until now, I had nothing against cowboy action shooting, which is more or less three-gun shooting with late 19th century firearms. If people want to dress up in period clothes, give themselves a western alias and shoot targets simulating stage robberies and saloon shootouts, that's fine. It's probably a lot of fun. I've watched it on Youtube. Some of those cowboy action shooters can really shoot.
They use lever-action rifles, single-action revolvers and side-by-side, pre-1899 pump, or lever-action shotguns. Again, all fine, except I learned a while ago that means some old Winchester Model 97 pumps get their barrels cut down to twenty inches, which isn't great, but, whatever. There are a lot of 97s around and they make a good riot gun. Then I found out that, since the coach guns on the market don't hold up well under the stress of competitive shooting, some cowboy action shooters buy old Savage Stevens doubles and cut them down. Well, okay, again, not great, but I can live with it. Those are good old cheap guns but hey, cowboy action shooters need shooting irons, too.
