I just purchased a 2" Taurus Ultra-Lite in 22 mag (model 941).
I haven't shot it enough to offer opinions yet, but at 17 oz it's closer to what I am looking for carry in hot weather clothing.
A better option would be the same pistol in 22 K-Hornet, as you could select ammo for deep penetration or frangible rounds.
The 22 WMR is a very decent round in close quarters, augmented by virtually no recoil/muzzle flip.
Machine a recess into the cylinder for a full moon clip and you are good for an 8-shot reload too.
