I seem to remember that long ago, shrouded in the mists of time, before plastic pistols and back when real handguns guns revolved, there was a large police agency that adopted a S&W autoloader. I believe it was the Illinois State Police and, at the time, it was considered a groudbreaking move.

Does anyone have any info on this adoption? Is there good, concise history of ISP's experience with the early S&W autoloaders posted anywhere on the web? Was it a good experience? What model did they adopt? What modifications/product improvements came out of this experience? How did the individual officers like what they were issued? How well did the ammo perform?

So much of the history of the LE adoption of many other brands/models is well known (Glock, Beretta, SIG, later S&W models, etc.) but I can't find much info on the pistol that apparently started it all.

No real purpose in this - just want to expand my general knowledge of my favorite pistol manufacturer!
