Wow -- joined the police department in 1970, and my first Duty weapon was a S&W Model 19 Combat Magnum. I carried it for years, until I broke down and bought the Model 66 (Combat Magnum in Stainless Steel). I carried a Chief Special for plainclothes assignments. One day I got a "wild hair" and bought a Colt Python -- shot it one time, and sold it to another officer on my platoon -- I didnt like it -- it just didnt feel right to me. I took the money from the Python and bought a Bodyguard to carry off duty, along with a Mauser HSC in 9mm kurz. I used those two off duty guns for off duty carry until I retired.
When semi-autos were approved, I bought a S&W model 59 and carried it for a short time, sold it and bought two (2) S&W Sigma 40v's. One, I carried constantly -- the other was identical to the first -- and I kept it in the safe except when the "constant carry" Sigma was in the "shop" for a new sight, or adjustment, or any number of little "piddly" things that are needed over time.
I carried the two Sigmas until I retired, never having one single bit of trouble with either of them. I found out with experience that spending a fortune on a duty weapon was fine if you wanted to watch a lot of money slowly deteriorate with on duty carry. The Sigmas were relatively inexpensive, but were more than adequate for on duty carry, with all the backing of Smith and Wesson. For the money they were (and in MY opinion still are) -- the best deal on the market -- and best deal for DUTY SERVICE if you are required to purchase your own service weapon.
All in all, they were the very best weapon I could have chosen, and if I had to choose again --- I would go with Sigma's with no hesitation.
