What does the S on a blackhawk cylinder stand for?
Should it be there on a 357 type 1 blackhawk?

the "s" is showing that it has been proof-tested with a proof load..all the center fire guns were stamped...except for maybe a rare case where they forgot or the stamp was weak... the rimfires were not stamped.
