When these first hit the market here in Australia, I thought WoW, I need one of these.
Then I handled one. 2x4 lumber offcut, single trigger, same firing sequence 123,123, no ability to barrel select & each barrel choked the same.
My dreams were crushed, not my type of gun.

Also, there are a lot of second hand, like new, fired one box of ammo, for sale here. They do not stick to their first owners very well it seems.

One guy who shoots pest animals off crops (licensed to cull) uses one with buck shot from a four wheel motor bike & loves it.
Better off with an auto I hear you say, but an auto is a special license here & a bit of a problem to get & keep. The triple gets him around that a bit.

Fun gun, but I can have fun with an English double & not only 2/3 as much fun.
