Well, no.
Because it really doesn't matter that much, unless you are spectacularly spacktarded, a deeply complicated task like pulling a trigger with either hand isn't really a challenge.

Granted, your natural preference to have the rifle nestling in your left shoulder would be a bit tricky to start off with, but as I said below, couple of spent shell cases to the face and the resulting scars would probably sort that one out.
