Gatsby,
You are the man on the Paradox guns, but......
this is a Climax action and not a Dominion.
Frank - this can be verified if you look at the action flats, there will be two hooks which protrude from the front of the flats which connect to the barrels.
Otherwise, Gatsby is correct, the dimensions indicate if the gun will shoot.
In my opinion, the cheapest of cheap Paradox's will sell for at least 5K.
