started to be made on alloy frames but they are not common.
Since the single stack steel frame 70S model in .380 all
Berettas sold in the US have had alloy frames as far as I
know until the recent polymer models. The predecessor of
the 9 mm 92FS model was the 951 single stack single action
model which had a steel frame.
