S&W 3rd generation pistols are some of the finest semi-auto Pistols made.
I think it's time to get back to stainless steel.
A retired MIL & LEO friend recently showed me his former duty pistol; a 3rd gen S&W 5906 stainless he was allowed to purchase from the Department with over 80,000 rounds.
He sent it back to S&W a few months back, and they went through it replacing a few parts, springs, new barrel, and polished it up like new again...
gratis & thanking him for his service.
Now that's what I call customer commitment!
