BTW, although everyone here knows this already, for the record, 9mm is ~.36 caliber (.355, to be exact, vs. .357).
9mm is .355 yes.
.36 is .375 not .357 in the time of these weapons & prior the caliber was measured by the lands diameter "Bore diameter" not by the grove diameter like todays standards.
A .44 caliber C&B revolver would nominally have a lands diameter of .440 but a grove diameter of approximatly .450 like a .36 caliber would nomially have a lands diameter of .360ish & a grove diameter in the .370's
