I nearly wanted the long barrel tracker version, but it only comes in 2.5" shotshell, but I also want one primarily to shoot clays one handed.
There is a Raging Judge coming with a longer barrel ( in .454/45/ 3" .410) that might be adequate, but the short barrel versions seem to have numerous reports here of being more effective to scare people past 3 yards with the Shot. ( low penetration unless a very lucky pellet hit, but not as much loss of power as say a Derringer in .410)
Not as cheap, but the 7" magnum research BFR supposedly has a better choke on it, but costs considerably more.
