bought today

so i went to the range today to get my license and get my first handgun. i was kinda fixated on the 19x prior to coming but i tried the 43x and the 19 gen 5 aswell. they all felt pretty much the same? apart from the iron sights on the 19 and 43x which felt easier to shoot with than the 19x but the advantages of the 19x overcame this and i chose it. the question that i have though is this: i've seen online that the 19x is generally for dudes with big hands and i'm certainly not possesing big hands. when shooting with it the gun felt fine and i wasn't feeling like the grip is too big to handle (lol). did i made a mistake by not opting for the 43x or even the 19?
