Maybe not the best way to put it, but there are other failures with revolvers beside the lock. The lock has been around since when? 2004? S&W builds 50-60,000 revolvers a year, seems to me I've heard more about firing pins, cylinder bind or barrels coming off. Don't get me wrong, the lock is about the most stupid thing they could of put on a revolver. I just don't see where the FTF because of the lock is greater than any of the other causes considering the number of firearms.
