Not really. The 686 has a full lug and came out over 20 years ago. IMHO the models that S&W intended to phase out the .357 Mag K frames are the recently introduced 619 and 620, which like the 686 are also L frames, but have the half lug like the K frames.Did the S&W 686 replace the old Model 65 (which I have in a 3" and love)?
Easy answer: Do what I did and get a used one! Chances are, it'll already be broken in so you won't need the trigger job (mine didn't need one) and no lock, either. I saved a pretty tidy sum doing so, too.And I don't want a new one because I don't want the stupid lock on it.
