I always had that extra little handicap. I am right handed, but my right eye developed poorly. I had an eye correction at a very young age, but right always remained a back-up, while my left eye became dominant.
I deliberately started training to aim with my right eye and it actually improved. But nowadays, to hit any target, I have to wait for the guide dog to bark twice before I pull the trigger.
Up until some 40 years ago, lefthanded writing was seen as a defect that needed to be fixed, quite common in Europe.
Our police did not get ambidextrous gun safeties until the late 1990s, when it became a requirement, along with grip straps for different hand sizes.
I guess we will get them in rainbow colors next
