Well yeah, you are being a bit anal, call it what you like and I'll call it what I like. I think perhaps the "long" designation may have come from the days when the army issued both the .45 Smith & Wesson and .45 Colt revolvers . The S&W round could be used in both revolvers but the "Long Colt" could only be used in Colt revolvers. There was quite a civilian business in both revolvers and I think perhaps the "long" designation may have come into use to differentiate between the two rounds. I really don't see where it does any harm, we often don't say exactly what we mean but most folks have no trouble figuring it out and since, as you said, there is no .45 short Colt, I don't see how it could cause any confusion.
