Many agencies still allow revolver carry but they are privately owned. I have seen several K frame magnums, a Colt Trooper, and two S&W N frames in LE use in my area. I still carry a wheelgun sometimes and always have a j frame snub for a backup. I do have a M10 and have thought about carrying it just because they are such a nice/light/accurate weapon.
Would be fine for off duty.

Most officers now tend to believe the revolver just doesn't
hold enough ammo to be offensive against today's brand of
turds, but cops have been facing full auto with revolvers
for years. Honestly, I doubt I will carry my wheelgun much
longer even though I really like it and am good enough
with it. 6 in the gun, 12 on the belt, and boxes in the car
is not all that much or fast. Revolvers are just so classic and reliable
though.

The 1986 Miami shootout spelled the end for wheelguns and 9mm
though. Those agents had a few 9mms but mostly revolvers with few speedloaders and boxes of ammo. A revolver loaded with Win SuperX 158 +P LSWCHP ended the fight, but most of those agents had revovlers up against a Mini 14/other long guns. It was interesting though that the revolver shooters aimed while the auto users sprayed and prayed. You cant spray and pray with a wheelgun or you will be in serious trouble.

I do think that Mexico and some foreign countries still issue
the M10 and probably with RNL ammo too.
