K-22 Masterpiece
I think the S&W K-22 Masterpieces (later known as the M17) are great revolvers available at relatively low cost. In the past month, I have stumbled across two, a five-screw built in 1948 and a four-screw from 1956. The asking price for the pair was less than the MSRP of the present M617, so the prices are right. These revolvers are also lighter than the present model since they lack the full-lug barrel. I really like the older barrel style since it is lighter.
These revolvers are great examples of S&W at the top of their game. Each revolver has an adjustable trigger stop, the actions are very smooth, accuracy is amazing, and the fit is a wonder to behold. There are no cost saving production methods used, so the front and rear straps are serrated, the barrels are pinned, and the steel is nicely polished. There are no internal locks to mar the appearance, and there are no MIM components. The 1948-model has a 1/10-inch wide front sight that allows very precise shooting while the 1956-model has the 1/8-wide front sight that is a bit easier to pick up in the rear sight notch.
Yesterday I put around 200 rounds of Winchester Dyna-Point through the five-screw model. I had no issues with hard loading or extracting. My first six shots at fifty feet could be covered by a quarter. Not bad for a 53-year old revolver.
