Some folks have opposite eye dominance than their hand dominance.

I do, and I carry for left hand draw despite being a righty for almost everything else.

There's also situational benefits to carrying off-hand, though I seriously doubt they apply here. It's just so much more likely that he shoots lefty and does other things righty.

That being said, handguns are typically a back-up, or emergency weapon, as opposed to long guns that are meant to be your primary arms. Some drivers will carry lefty even if they're right eye dominant because if they need to shoot while driving; having the dominant hand on the wheel is more important. Same for people that might need to operate other machinery while shooting. Like I said, very situational.

Joke reason : he's a radical leftist, where else would he carry?
