If you can find one, a used example is I'd reckon in the 850 ballpark. But as smokeless said, 3 inches at 35 yards, I'd want a lot more for the money!My .36 Uberti Navy will do that and it cost 70 quid! And the Rogers & Spencer is also on par for a couple of hundred quid!

That being said, none of the alternatives to "proper" handguns have really taken off. The fact is, some of this stuff is just a poor second. Long barrel revolvers by Taurus and Ruger will sub 2" with work and the right load and the long barreled Browning Buckmark is a target pistol. But with a 12" barrel and an steel rod over hang to take the length to 24", it's not the same as slamming a mag into a 1911, racking the slide and storming "El Presidente"!

In fact Morini made a dedicated .22lr free pistol to conform to UIT, but again at 1200 pound plus, they obviously wouldn't get many takers for such a dedicated piece of kit.
