Any of the 3" K frames are hot right now. If I was offered that revolver at $450.00 I'd buy it, ASAP.
I have a 3" M 65-5 Lady Smith, it's a pleasure to shoot with all types of ammo, has a great balance, and is more accurate than I am. Yet somehow it feels much heaver that my 2 1/2" M -66.
Good luck....
