Nice revolver, Deputy.
I picked a new 6 inch Model 66 as my holster gun when I was sworn in as a deputy sheriff on November 9, 1981. I went through POST with it and then carried it daily at work for the next 10 years.
Early on, as soon as I could afford it, I bought a second M-66 just like the first one and sent it back to S&W. At the time, they were shipped with a red front sight insert but a black rear sight blade. I had them replace the narrow, grooved service trigger with a wide, smooth "Combat Target" trigger, perform an action tune, and add a white insert blade. As soon as I got it back, I put Pachmayr Presentation grips on it and sent the first one back for the same treatment. It was a great idea, I thought, to have a second, identical duty weapon available in case you lost yours, it broke, someone took it away or one was just dirty from a range trip and you didn't have time to clean it before your next shift.
It was a policy I kept over the years as I changed guns.
I loved the Model 66. Carried in a Safariland high ride holster, it was easy getting in and out of cars, as well as just sitting in them. The power of the cartridge was just right. The stainless steel resisted the elements and cleaned up well. The light weight, compared to other revolvers firing the same cartridge, was important as more and more gear was added to our belts and the six inch barrel helped tame the muzzle flah and blast, compared to the most common 4 inch barrel, with the Federal 125 grain j.h.p. Magnum rounds I carried. For me, at the time, it was nearly perfect. I shot it well. It gave me confidence. I later swapped the Presentation grips for the same firm's "grippers," much the same but with finger grooves that actually fit my hand.
For cop or sportsman, S&W's stainless Combat Magnum is a tremendous handgun.
