I remember when Taurus introduced their new 9 shot 22 magnum revolver. It weights 55oz, That is more than their 454 casull Raging Bull! The Ruger SP-101 22 weights in at (reportedly) 30 oz. The model 63 weights 26 oz. I would say that the Ruger is not too heavy but the Smith would be my choice. I would rather have the model 18 combat masterpiece over any of them. The only 22 revolver I own now is a Ruger Single Six "Buntline" with a 9.5" barrel. It will deliver amazing performance from the 22 magnum cartridge.
