In a previous reply to this thread, I mentioned that I purchased a 629-4 with a 6 1/2 inch barrel with the power port. After shooting it, I noticed that the front sight was leaning to the left as a result of the barrel being turned in too far.

I decided to call Smith & Wesson customer service, and they recommended that I send the gun in for repair.

From the time I sent it to Smith & Wesson, until the time I received it back repaired, was a total of 9 days. They repaired the gun under warrenty. They told me that Smith & Wessons made from 1989 on, have a lifetime warrenty.

I was very impressed with the short amount of time it took for the repair which included the mailing time. A total of 9 days.
