I had one of the first 329 scandium 44 magnums off the line. Serial was a double digit.
I had the lock engage twice in the first 50 rounds. I called S&W and they sent me a shipping lable to sent it back to them. They pulled it apart, cleaned and inspected it. I had it back in my hands in under two weeks.
Next trip to the range within the first two cylinders I had it lock up again. I emptied the cylinder and left it locked. I sent it back with it still locked up (they gave me another shipping lable).
I got a call from someone a few days later with a string of apologies... But no solutions to the problem...
I explained I no longer could trust the gun and didnt want it back. He understood and a week later I got a check in the mail from S&W for the full price I paid with tax and FFL fees.
That was the last scandium pistol I bought. Will never buy another one with a lock. I would love to buy another one in 44, but not with those stupid locks....
