S&W made a small group of Model 19-3's with 2.5 inch barrels and square butts in nickel, in the late 1970's for the NC State Highway Patrol senior staff and helicopter pilots. I can remember seeing some of them at that time. A friend of mine worked for Davidson's in Greensboro, NC and he delivered the guns to the SHP Headquarters. The SHP Colonel (Commander) had them built because the four inch guns's grips "poked" him in the side when he sat in his chair. As S&W was in the business to sell guns and the NC SHP had 1200 members at that time, they gladly built them.
