Yeah, this happens more often than enthusiasts and 'brand aficionados' might care to realize.
I can think of a couple of other brands (meaning not S&W) where major state or county agencies had problems with components in new guns, and the gun companies had to scramble to replace major components in just a couple hundred guns from a production run, or in a couple thousand guns, if they wanted the agencies to stay with their products. These sort of things don't always make the news or find their way into public attention.
Sometimes it doesn't serve the interests of either the agency or the gun company to air out such things in the press. Sometimes it happens, though.
