I had a Colt's Detective Special. An old one, with an unshrouded ejector rod and the most gorgeous Royal Blue finish you could imagine. I don't know how many special Bluing Gnomes had to be paid to hand polish that thing with imported silk hankies by the light of a full moon, but it was worth it.
On the other hand, just about every street cop I know in an urban or suburban area prefers a stainless CCW gun for their greater "presence". As one police officer friend of mine said, to justify toting a .44 Mountain Gun off-duty: "When you pull a 4" stainless N-frame out of nowhere, you have everyone's undivided attention; there is no doubt in anyone's mind that 'That man has a gun!'". I'll have to agree; it's hard to find a firearm more imposing to be on the wrong end of than a 625, without moving to slide-action smoothbores...
