I have a Heritage RR .22 6 1\2" bbl, a Taurus Gaucho 5 1\2" bbl (a Colt SAA clone) and an 1858 Remington 8" bbl repro. The Heritage is physically the smallest in both size and weight. The Taurus IMO is a beautifully balanced gun and has a beautiful trigger action. A joy to shoot. The Remington being a much larger gun than the others is heavier and physically larger than the other two. It is still well balanced, just feels a lot different. If you were looking for one that more closely resembles the balance of your Heritage you might look at the 5 1\2" bbl model although it will still be larger and weigh more than your Heritage. A lot of people like to look down on Heritage .22 revolvers but for the price they cannot be beat.
