All of mine with one exception are police issued service revolvers:

1) Colt Border Patrol (Alabama D.P.S.)
2) Colt New Service (Androscoggin County Maine Sheriff's Dept.)
3) S&W Model 13 (Anchorage AK PD)
4) S&W Model 66 (Cass County ND Sheriff's Office)
5) S&W Model 66 (Ga. Alcohol & Tobacco Taxation Unit)
6) S&W Model 686 (Iowa State Patrol)
7) S&W Model 19 (Israeli Police)
8) S&W Model 586 (Jicarilla Apache Police -New Mexico)
9) S&W Model 65 (Mass. Registry -Motor Vehicles)
10) S&W Model 66 (Minnesota State Patrol)
11) S&W Model 66 (New Hampshire State Police)
12) S&W Model 586 (Seaside OR PD)
13) S&W Model 66 (Wyoming Highway Patrol)

....... and a 4" S&W Model 13 that I carry off duty. It is probably a service revolver too. But, I haven't lettered it because I want to keep it in the carry rotation! )
