The first one issued to me on the first PD I was on...S&W M10 HB. Those were exciting days being a new officer and the M10 seemed all business to me. I later bought a Colt Combat Commander in satin nickel that I carried in a shoulder holster under my uniform coat in cold weather and in a Bianchi Pistol Pocket when off duty. That M10 had some substantial wear on the finish but was in perfect mechanical condition and the trigger was wonderful. Using that revolver and department practice ammo I learned to shoot a DA revolver with some good effect. Some of the detectives were issued 2" M10's and some 2" M15's. I left for another dept before getting to that stage in my career and never carried one but I have a nice M15 snub now.
