I have a "no dash" that locked the cylinder on the first box of ammo (win 158gr .357). My dealer sent back to S&W for a new firing pin and bushing, and an M stamp on the frame. The M model uses the same firing pin and bushing that became standard on the 686-1, so it's no big deal. I have my 686 "M" and its been flawless sinceForgive my ignorance: what is the M modification stamp/work?
The -4s. But anything pre lock, just because I like the hammer mounted firing pin and no hole.
Sir, You are correct the-3 is the best versionMy preference is for the -3. It's the last rendition with a square butt; I prefer that because there is no factory target stock with beautiful wood figure for round butts. I once traded a mint 4" -4 for a -3 just to get a square butt gun. I installed a target hammer and trigger but all I could find was color case hardened. For a -3 they should be flash chromed but I do like the old school look of these. This gun had obviously been polished which I don't like so I have been thinking about having the brushed finish restored.
