If a six inch barrel K-frame was the only gun you had, then carry it because it's better than being unarmed.
That said, IMO that's a duty gun (from 30-40 years ago) that belongs in black basketweave along with your cuffs, Mag-lite and speed-loaders (or has been said in earlier posts, a good shoulder holster if you were an inspector); at the first opportunity I'd be on the lookout for something a bit easier (and lighter) to hide.
Unless your name is Callahan or Crockett a big, heavy gun in a shoulder holster gets old fast. Been there, did that, and changed to a snub nose real quick, especially in warm weather.
