What WAS that gun? Not too long ago, somebody posted a very nice picture of a Colt revolver, silver - stainless, I guess, that had a red ramp front sight, a Trooper-ish looking frame and ribbed barrel, like a Python. What WAS that gun? I've looked up the King Cobra and they don't have the ribbed barrel. Don't know what else to look up - I'm just stuck. Help?
