Nah, it's not so bad.... of course I don't desire some of the things you do (Crimson Trace for example- Laser Max guide rods might work for you on some weapons). And I shoot long guns mostly right handed.
But the 1911? The only thing we need for that weapon is the Ambi safety (IMHO, something the right handers need too). The rest of the controls work (maybe better) left handed. Magazine release? Trigger finger (hard to do right handed with thumb without changing the grip position some). Slide release? Either trigger finger, support hand fingers from underneath or simply "slingshot" it.
As to holsters, my issue there is minor too, as I've largely gotten away from the stuff in stock at gun stores (bought a lefty Galco in one a few years back though). Most of mine these days come from Sparks and the like. Equal treatment there! I did buy a "Bodyguard" from DM Bullard a few months back, and he had lefty's in stock.
In general, I do understand what you mean. Scissors are a bear (yeah, you righties never thought about that! Try working a pair left handed!). And we need to ensure we are seated correctly at gatherings to prevent the usual elbow conflicts. And virtually everything is designed with right handers in mind (try a circular saw with the left!). But all in all, there are positive aspects (let's look on the bright side, we're unique!
).
Hey, according to science (and an old saying), we're the only ones in our right minds*
*Refers to a brain dominance thing, left side of the brain controlling right side of body, vice versa....
