I wrote S&W about purchasing a 9 round magazine that will function in a M639 9MM. Mr. Paul Remillard (S&W) E-mails me that "they" are baffled by my inquiry because the 639 magazine already holds 9 rounds. As an owner of 2 (now 1) 639s, I must be mistaken as I've only been able to load 8 rounds in any of my 8 Model 639 magazines since 1991. The guys in customer service sniffing White-Out, or what?
