Bought these two S&W pistols back in the mid-80's, just when the 2nd generations came out. The M645 represents S&W's first foray into the .45 auto market...and was on a TV series, carried by Sonny Crockett (Don Johnson) on the 3rd and 4th seasons of Miami Vice. The M659 was carried by Larry Zito (John Diehl) on the same series.
