S&W K frames are easier to shoot and have much better triggers then the J frames (kit guns). The J frames are available with 6" barrels, by the way, you just don't see many of them, sort of defeats the purpose. Colt Trooper Mk III revolvers are good shooters in this caliber, in SA revolvers, Ruger and Colt rule the roost. I prefer the Colt New Frontier (I have two), but I have owned the Ruger in the past and have no problem recommending it to people. If you"re buying new, you will probably only find the Ruger Single Six convertible on shelves. 22 Mag ammo is very expensive compared to 22 LR, which makes a switch cylinder a better economic choice, though not necessarily a more accurate one. FWIW - dan
