S&W made the model 650 for a while, it was a fixed sight J frame. Most were .22Mag but I bought one new that had both a .22RF and a .22Mag cylinder. Several years later I made one of my "seemed like a good idea at the time" decisions and let it go............wish I had it back. The 650s are scarce but show up rather regularly on the auction sites, pricey but not in the M-45 range. If S&W would make a run of M-45s I'd buy the first one I saw. Keep shootin'
