Ah, I did not realize there were both revolver and semi-auto Chief's Specials. I got the .38s this year, two of them for a deal I could not pass up in March, as well as a Model 28 but not in .357 instead it is .41 Magnum. These are all six-shooters too, so I think the .38s are K-frame. My one other classic S&W, a J-frame .32, is also in the group but bought about a year ago.Mine is a J frame made in 1978. S&W keeps changing stuff on me!
