I've removed the MP38 from this fix so that it's firing sound works once again. I simply altered two lines of text, I am a pro.
This fixes all automatic weapons (except the MP38, now) so that they won't occsaionally play the gunfire sound twice when tapping once.

Credit to 90e and DarKobalt for the original fix, some reddit user (?) for the updated code, and AdayDr1en for porting it to RAID: WW2.
