I've got a new 640 Pro which has been in for warranty service several times. It went back to S&W for a dead night sight before I even took it home from the dealer. It was returned with a new night sight, a new barrel, a new yoke and scratches EVERYWHERE. Test fired it before sending back again it and was keyholing. Barrel cylinder gap was also crooked, .008 higher on one side than the other. They returned it to me with another new barrel and yoke but did not address the obviously bent frame. Sent it back again and they destroyed it and sent me a new one. The barrel cylinder gap on the new one is a VERY snug .002. I almost feel they did that to spite me. Can it reliably run at .002?
I'm exasperated.
