I have a Model 67 with a 1 over same Ser. #3K89xxx that I got in a swap with a fellow officer as he wanted my Chiefs Special as he was going into the Detective Bureau and it was too heavy for him to carry. I wound up carrying it as a duty weapon and went to the NJ Bergen County Police range to qualify with same. Qualified with a score of 150 out of 150 all double action, it seemed like I was in the groove while firing . I blackened the back of the rear sight with a laundry pen and using a yellow lumber crayon stippled the back of the front sight, the backstrap and front strap were naturally grooved as well as the face of the trigger and with a two handed grip and bent at the knees I couldn't miss the black. Well they couldn't believe what I fired and had me do it again which I did. The range officer tried about a dozen rounds and hit the black every time. He couldn't believe how that trigger was so smooth in Double Action and in single action it was like he was using a cookie cutter on the bullseye, I then copied him doing the same. He asked if I had it tuned and I said thats the way it came from the factory, no work ever done on it. I only put about 500 rounds down the barrel before this and it was the same then. I have put about 5,000 rounds thru it since then and is still as accurate as before.
