I wouldn't agree. I own and shoot multiple examples of both and have had issues with both. Those that have issues get a trigger job.

The last S&W I acquired is a Model 14 from the late 60's...I figure probably 66-67. Beautiful gun, great trigger and the tightest throats I've ever encountered on a revolver. Probably why it wasn't shot much.

A few experiences with other pre 1970 S&W's vs more modern guns leads me to believe that while the fit and finish on the older revolvers was superior I'm not at all sure about their actual machining tolerances. I see a lot more variance in older models.
