Hi, Savit260,
It doesn't really matter to me, since I am not going to buy the gun anyway, but I have known Colt to claim they didn't make something when they clearly did. I have a 9mm Combat Commander with a barrel marked ".30 Luger." It is a safe assumption that they had an overrun of .30 Luger barrels and simply redrilled and re-rifled them to 9mm.
I thought an actual .30 Luger Commander would be neat, and called Colt about getting a barrel. They claimed they not only didn't have barrels, but never marked any barrel that way, and never made any gun in .30 Luger. The gentleman questioned my sanity and my eyesight, and said the marking must have been put on by someone as a joke.
I found later that they made a fairly large number (2000 comes to mind) of .30 Luger Combat Commanders for sale in Italy, where ownership of military caliber guns is banned. I still have not been able to find a .30 Luger barrel for my Commander, though.
