Thanks guys . I guess I was wrong , mine is the second round . Looking at the serial#s , I'm guessing they didn't make many . You look at the 3rd run and their numbers start low . But then when you're dealing with S&W , nothing is set in stone . I just noticed , both are listed as having an ambi safety . Does that count the grip and thumb safety ? Also , what constitutes a match grade magazine . Again , thanks for all the help !
