Does anyone know when the last single action revolvers were used in US law enforcement? When I was a kid in grade school all the cops had Smith (and maybe a few Colt) DA revolvers, but can anyone tell me when the last single action wheel gun was put out of service to make way for the double actions. I'd like to guess that there were some still being used in the twenties and thirties in rural states, but I'll bet some one could surprise me with some info that they were used much later then that in some places. I have a realtive that was a Cop in an urban community in Northern NJ just across the river from NYC. He told me that they still had a 30.30 lever action Winchester Model 94 in their arsenal in the mid 80's. Any other stories of old guns officialy used by cops lately?
