I think the RCMP issued the 5946 or 5943. Isn't that what the Sgt at Arms of the Canadian Parliament used to stop the attack a couple of years ago?
As I recall the 59xx is no longer issued to NYPD, but those that have them still can carry them. Well, as I recall from a different part of the forum, there is at least one NYPD Sgt still carrying a S&W revolver.
LAPD still authorizes officers to carry 3rd Gens, and again I remember a recent thread where an officer recertified with a 4506.
Are the WVSP still using their Melonite 4566TSWs?
There are probably small agencies and individual officers with discerning taste in firearms that still have 3rd Gens in their holsters.
Then there's us!
