I've owned and enjoyed examples of S&W autos from all 3 generations, and wish I'd kept many of them. In any case, just took a photo of the only S&W autos I have left, all 3rd. Gen.
They are Performance Center DPA 5906s with 5" and 4" barrels, a 3913, a Performance Center CQB, and a 1026. I carried the CQB every working day for a year and a half or so, and it shows it. All have displayed the usual 3rd. Gen. boring, and much appreciated, reliability.
