Well, until the 50s, barring a few places like Shanghai PD, formal target shoots was 'combat' shooting.
There was some "cup & saucer" revolver shooting in the ancient days of PPC.
Army WWII training for "combat" shooting with pistols was all one-handed, "reflex" shooting, often eschewing using the sights at all.
OP was asking about photos of shooting, without specifying a particular way of shooting, so, that was what I was trying to address.
Combat shooting is relatively modern (ok, close to four decades old now) in terms of being two-handed deliberately aimed fire using sights. The advantages of supported shooting are just too obvious to ignore.
Which did not stop various gunwriters from trashing each other in flames wares using barrels of ink in the 70s & 80s for publishing their heresies.
