Beretta firearms produced in Italy carry a proof mark for the year of production. The chart below is used to identify the year by this mark. For recent pistols this mark is usually located on the frame near the trigger guard, for older pistols, the mark is on the slide or on the frame behind the grip area. Shotguns have this mark stamped on the barrel near the chamber. You may need to remove the barrel to read the mark.
In some cases the actual date was stamped instead of these marks, this is normally seen on older pistols.
We have also seen markings where roman and numerical figures are combined, for example XX 8 instead of the listed XXVIII for year 1972.
