Older S&W Model 17,,the 6 in barrel or Model 18,,the 4 in barrel. The difference between the older ones and the new 617 is night and day. Honestly, the 617 6 inch I had a couple of years ago was such a lemon that it would turn anybody off of shooting for a lifetime. Mine was terrible and I hated it! Keyholes, and misfires were common place. It wouldn't shoot an entire 10 shot cylinder of ammo on the first strike. Accuracy and reliability were non-existant. It was way off balance with the full underlug and 6" barrel. A real POS.,,,strike that,,,at over $400.00 a real EXPENSIVE POS.
Dan Wesson also makes a fine .22 revolver, as does Ruger and Taurus.
Again though, the difference between them and the older Smiths triggerwise is night and day.
