I “borrowed” my dad’s guns while in college. After I graduated, the first gun of my own was a Remington 870 12 gauge left-hand. My second gun I bought was a Remington 700 30-06, also left hand I love them both. Shooting right-hand guns was a pain.
I’ve always shot rifles and shotguns left handed. Never got one that was specifically for lefties. Yea, I’ve had a few hot shell casings down the sleeve, but it’s not that bad.
I started shooting pistols left handed...couldn’t hit sh**. Had a weapons expert do a dominant eye test on me. I am right eyed. Started shooting pistols right handed 20 years ago. I’m not a great pistol shot, but I can knock a man down at 60 meters. You have to love the Army’s pop up .45 and 9MM ranges.
