625-3 in .45 Colt 1989 model

Not every one...

Greetings and welcome to the forum.

The model 625-3 was never produced in 45 Colt Cartridge, period.

Any revolver Smith & Wesson ever produced in 45 Colt said just that on the barrel 45 COLT CTG.

My 25-7 doesn't have "Colt" on the barrel. There's a big 45 Colt thread that you might be familiar with, that has pictures of a 25-7 without "Colt". The 25-7 seems to have barrel markings similar to the OP's revolver.
