Sig Sauer P239 Threaded Barrel 9mm M13.5×1 LH Black is the configuration on this listing. No separate caliber is printed on this listing, so this description does not invent one. The listed thread is M13.5×1 LH. The listed color is Black. Additional information repeats only the stored manufacturer, model, and the fields that came with this row. If a measurement is not in that list and is not in the name, this page does not supply it. Nothing here states an overall length, a weight, or a sound rating.

When two Sig Sauer listings look alike, compare caliber, finish, color, and model name only where those fields are filled in. This page is Sig P239 Threaded Barrel 9mm.
