In my case, I am left-eye dominant, but did not understand that part when I first learned to shoot. Several shooting instructors, over the years, have noticed I seemed to be cross-dominant, when seeing me shoot right-handed, but things are not that simple: I am left-handed with small, skilled tasks, but right-handed/armed with larger, more-gross-motor-skill movements. Drawing large, heavy revolvers from my first low-slung duty rig being a lot like throwing, well, I decided to carry at 0300 in 1983, while attending the police academy. There was no general legal carry for private citizens in Texas in those days, I had only recently been able to buy a handgun, and I had lived in a non-handgun household, anyway, so I had not established a "weapon hand." Plus, my low-slung carry duty rig was not easy to reach while seated inside a vehicle's driver's seat, reinforcing the practicality of carrying right-handed.
Most DA revolvers being caveman-simple to shoot, it really does not matter which hand I use to shoot them*. Pre-Gen4 Glocks work better in my left hand than in my right hand. Gen4 seem more hand-neutral. Some of my best 1911 groups have been shot left-handed, but my best one or two groups were shot right-handed.
An immediate side benefit, back in the day: A shooting session with big-bore Magnums would largely spare my writing hand, as I mostly shot right-handed, working from the holster.
A delayed benefit: Today, my right thumb and wrist cannot tolerate much recoil, but my less-abused left hand is still relatively healthy, and, it just so happens that pre-Gen4 Glocks, and some revolvers, are my favored lefty handguns.
With long guns, my shooting performance often sucked; I was a mediocre shooter with long guns, until I understood the importance of shooting long guns from the shoulder corresponding to the dominant eye. Actually, one reason I preferred plain-bead-sight shotguns, with no rib, for so long, was because they were eye-dominance-neutral for me. Some open sights, on rifles, are OK when I shoot right-handed, but with aperture sights, or optics, or with a vent-rib shotgun, it is important for me to shoot lefty.
*My hands are built a bit differently, so an individual weapon's grip dimensions and trigger reach may favor one hand or the other.
