I've got one of these. it's a joy to carry.
I can only think of 2 guns that might fit your criteria. One of them is not a revolver. The 1st one would be a Taurus total titanium model 85 chambered in 32 H&R magnum. Very light and a respectable cartridge. The 2nd one is a double tap derringer in 9 mm. It is light and dependable though the recoil is stout.
You might have to search around a bit to find either gun but if it's worth having it's worth looking for.
I see gun control as waiting in an ambulance at the bottom of a cliff when we should be building a fence at the top!
