Time perspective of the young really amuses me. Up until the late 1960's a handgun was shot with one hand except for women and any man who shot 2 handed was under suspicion of being less than manly. You won't see pictures of the great pistol shooters like Skeeter Skelton, Jeff Cooper and others of those days using a 2 handed hold. About that time I read an article by a respected shooter that proposed using 2 hands to shoot as he said the targets proved it increased scores. As it was slowly adopted in the 70's by police departments, driven by competition shooters using 2 hands in new games and matches sponsored by new organizations like IPSC founded in 1978. Two handed handgun shooting is now probably the predominately common way a handgun is shot. I know several people who prefer to shoot with a one handed hold, many are much better with one hand than I am with two. I shoot in a Bullseye league and find no difficulty shooting one handed accurately. Two handed hold offers a bit quicker recovery under recoil. The old man we knew as "Coach" who had a shooting box full of medals won over the years would remark that a pistol is called a "hand" gun, not a "hands" gun when asked about using a 2 handed hold.
