Bought new Model 60 (1975) no problems; bought used Model 19-4 (1975/76ish?) no problems. Bought new 627 (late 2010) it has obvious flaws. In 2 weeks I pick up a M29-4 used, I will post my finding after some time with it. I'll have four S&W's and they are the ones that suit my shooting hobby fine. If they have some issues I'll address that and try to keep and be happy with them. My S&W collection will stop at 4, and it's not a quality control issue, it's just that 4 is enough for me.
