Methinks one should add the S&W 5906 during its time was also the duty pistol of nearly every policeman in the U.S., largely but not completely displaced - oh so slowly, at that - by Glock, primarily but not solely.
Nevertheless, PDs still are trading 'em for newer sidearms some 20 years following the 5906's end run.
However, especially when examined is the totality of the 59xx series (5903, 5903-SSV, 5903TSW, 5904, 5905, 5906, 5906 NS, 5906 Super 9, 5906-M, 5906TSW, 5924, 5926, 5943, 5943-SSV, 5944, 5946, 5946, 5946TSW, 5967 as well as short-run special models, e.g., Lew Horton and Tim Horton ((well, 'police,' 'short run' and 'doughnut glaze' all kinda go together, right?)) as well as the series' run time (11 seasons for the 5906), the 5906, alone, was among the most-produced firearms found anywhere and of which nine examples grace my vaults.
Truth be known, as a shooter the '06 isn't one of my favorites. As a collector, though, I'd be grossly remiss in failing to take note of its considerable contribution in cementing the 9mm parabellum as a central part of shooting habits in the United States.
Later.
