For a revolver, think about the Charter Arms Bulldog - .44 Special.
Nice and compact, easy to control (at least for me).
Mt dad and I are into all kinds of guns, revolvers, pistols, shotguns and rifles.
As far as sidearms go, he has a 1911 and the Bulldog.
I have 2 EAA Witnesses - .45 and 10mm both full size, a Beretta Model 81 .32 ACP, A Makarov, A CZ 52, a Ruger Redhawk .44 Mag w/ Weaver stainless scope, Two Ruger .22 pistols - one long barrel and a long barrel target model as well as a High Standard .22 Mag derringer.
For some reason, I am more accurate with full loads in the 10mm than I am with any other centerfire sidearm except for the Redhawk - but it has the scope and is HEAVY! The 10mm is actually my last sidearm purchase.
Sorry to go into great lengths, but it boils down to what others have said - you have to find the sidearm you are most comfortable and accurate with.
Just a note, I have a medium to large hand - if I have to wear latex or tight gloves I take a large, but for normal winter type gloves a medium usually fits - I HATE loose gloves.
