Though, I sympathize with the gent and his model 642. I purchased a Smith & Wesson Model 48 Classic from the Fort Bliss PX back on Sept 3 2016 for $570.00. The pistol was “New”, but I looked at this pistol on and off for over two years prior and watched it develop a turn line on the cylinder as one clerk or customer dry fired it during that time. I knew it would need a new firing pin when I purchased it and called S&W Customer Service once Labor Day was over with. I clearly explained the situation to S&W and was told with a chuckle that’s its “no problem and we will get it right”. Three weeks later I got the pistol back with the repair invoice that the firing pin, main spring and CYLINDER were replaced. Pistol looks great and shoots even better. I’m a happy S&W Customer.
