I had one issued to me in 1976. It was a 4" blued model. It eventually loosened up. I could grab the barrel in my left hand and grip the grips with my right hand and there was noticeable movement in the frame. I turned it back in and got permission to carry my S&W model 28-2 after passing on a Colt Trooper model, which had a trigger with a hefty, long pull that would require a grown man and a young boy to manipulate. Years later I was issued a Ruger Speed Six with 2 3/4" barrel. It was a reasonably accurate, solid and shootable revolver.
