I bought a Centennial 442 from my boss, as a "parts gun", for $25, as it had a yoke-crack.
I sent it back to S&W, and it was replaced with a new gun, but with same serial #, avoiding complicated state paperwork. When I told my boss (just before retiring), he was livid.

Totally unlike my experience with dealing with a BMW motorcycle over cracked frame welds...the process took a year (under warranty), half of which was waiting for a new VIN sticker, making the bike to be unsaleable in the meantime...Loved the bike, but that was unacceptable warranty service. Migrated to Honda and Yamaha after that fiasco.
