Any former Diplomatic security service officers here?

What dash number model 19's did you use? I've seen 19-5 2.5 and 4" barrels. Most of those were in a matt black. I also have seen 4" matt black 19-7's, supposedly former DSS guns. Were any of these model 19's traditional blue, or were they all in a matt finish?

I read where the USMC also had ordered a large number of model 19's, to use for guarding embassies. Any details on those model 19's?

Anyone lettered their matt black model 19?
