My absolute favorite revolver is an LE trade-in Model 64 NY-1. DAO, of course.
Years ago, it was about $200ish from one of the big surplus dealers, Century IIRC.
Sent it back to S&W to have the vapor hone finish renewed and a "combat revolver" job. Back when they knew how to work on revolvers. Papers signed by "Vito".
DA is silky smooth, ~ 6 pounds.
With my 158 grain handloads it shoots to the sights at any reasonable range. Especially good on the steel.
Just picked up a spare cylinder that's going off to TK Custom for a moon clip conversion. Soon be able to shoot it even more.
That's my favorite LEO gun among several others.
