Okay, at first glance this is a weird one:

Now before everyone starts falling about with laughter, let’s just look at what this piece brings to the party.
One of the problems with the similarly-chambered Taurus “Judge” revolver is its size:

I mean, that lo-o-o-o-ng cylinder makes it a monster, which makes it problematic in terms of its utility. You can’t carry it comfortably and frankly, the shorty barrel makes it unpleasant to shoot. (Ask me how I know this.)
While the little .410 shotgun shell is a weeny compared to its larger cousins in 12-, 16-, 20- or even 28ga, it still announces its ignition with a very meaty slam into your wrist if chambered in a handgun. (I once owned a Bond Arms Derringer in .45 LC/.410ga, and shooting it was an ummm interesting experience.)
Frankly, therefore, a handgun chambered in .410ga is not really a viable or even pleasant proposition.
Now let’s look at that Rossi Circuit Judge again.
In a stroke, it does away with all the disadvantages of the .45/.410 revolver by adding a longer barrel (helps with recoil and ballistics) and the shoulder stock turns it into a handy little carbine.
Ignoring the .45 Colt part for a moment — because we all know and love the old cartridge for its deadliness — what this Circuit Judge brings you is a tiny and manageable .410 shotgun, with six rounds capacity. Find me another .410 shotgun that compares.
Would I want a Circuit Judge for myself? No, because I have no real need for it. But if I lived in an area where potting crows and rabbits and such is part of an early evening’s entertainment with friends while sitting around a fire pit with a glass or two of single malt at the elbow, such as at Free Market Towers in Hardy Country…
…I’d buy one in a heartbeat.
