I am retired now, but for 15 years as an Active Reserve Deputy Sheriff, and another 2 years as Police Chief I carried a 4" Power Custom Combat S&W 610 No Dash most of the time on my duty belt. I carried in a Tex Shoemaker Semi Breakfront Security holster. In 1993 I felt this was the most secure holster built that you could do a reasonably fast presentation from.
I custom made a Black Basket Weave, Quad Moon Clip Belt Carrier for it. Two up and Two down.
I have been retired almost 4 years now, and my duty belt is still hanging in the closet ready to go.
If I were going to get back into Law Enforcement, Which I am not by the way. I would go back to carrying the 610.
I like revolvers, and I like the power of the Full House 10mm. My gun fights were all with Deer hit by vehicles. The 10mm did a very impressive job putting them out of their misery.
I only had a weapon pointed at someone one time during my 17+ years, and it was a Scatter Gun Tech TR870 Remington.
Anytime I was expecting a problem I got out the M4 or 870 to start with.
I have never felt under gunned with a revolver, since my first patrolman job in 1974/1975 carrying a Model 28 in a Bianchi Border Patrol Rig.
