To the OP, whatever works for you. I have seen guys shooting right-handed rifles from the left.
Let me get everyone's cogs jammed up.
I am left-handed. I carry my 9 mm on left hip in an OWB holster under a large shirt.
I shoot long guns right-handed. It has to do with options back in the 70s. Our scout master was teaching us to shoot 12 ga. And it was a semi-auto. I was raising it to my left shoulder and he told me to move it to my right. I learned why, instantly.
So, I just kept that up.
In 1974, Just before we were going to move from California to Texas, I picked up my step-grandfather's Sears Silvertone guitar with only 3 strings left on it. And started picking out the arpeggio beginning to "Who'll Stop the Rain?" by Creedence Clearwater Revival. I was doing it right-handed, which felt right because the left hand is doing all the work.
We get to Texas a few weeks later and my mother gives to me an acoustic guitar my father had given her (he was a music major when he was at the University of South Dakota before transferring to UCLA.) All she could afford was Mel Bay's Book of Chords. My step-grandfather taught me how to read sheet music.
Anyway, I surmised that playing guitar right-handed is really a left-handed activity.
So, in the end, do what feels comfortable. And, these days, there are more offerings for left handed actions.
