I found this amazing video featuring the LA Sheriff's Department Pistol Team.
RARE - LASD Pistol Team Exhibition, Historic, 1936, Color enhanced - YouTube
It covers their standard training, stunt/exhibition shooting, lots of range footage, and plentiful information on their reloading and bullet casting operations.
I think the revolvers used were mostly Colt Officer's Models. But, maybe there's a S&W 38 M&P in there somewhere, too.
I especially enjoyed the information about the reloading, bullet casting and range operation and logistics near the end.
Great to see a strong training foundation in fundamental marksmanship and "Bullseye" technique.
The "combat" range and methods look pretty interesting, too!
As for the exhibition shooting, I wouldn't want to be assigned the job of holding targets in my hand or mouth!
Hope Y'all enjoy it as much as I did!!
