In a 5" 9mm I got the Berry 115gr plated up to 1350fps. (+P)

Best high end accuracy was at 1257fps that is near a NATO spec.
My minimum fps full loads came in at 1198 and 1218.

So care with the 38 Super loads is needed, do to higher fps that it can put out.

Most powders with the 124gr bullet are safe in the 9mm but I did
get this heavier bullet up to 1257 and 1267 with two slow powders, so use care.

Accuracy came at 993 up to 1155fps in my 9mm with the 124 with
a oal of 1.14".

For some odd reason my 5" does not like plated bullets with short OAL.
A 115 ball at 1.10 and a 124gr ball at 1.09" did not do any better than a 1.14" OAL in my test.
Your 38 Super might be different in its OAL that it likes as well as
the speed of target up to medium heavy loads.

Safe shooting.
