Massad said: "It's less about gender than about hand size"

I'm a male of above average height, but I have come across guns with grips too large for my hands, and stocks too long to comfortably sholder.

If I had a giant wife, who could, like you, handle anything out there, I'd want to make sure that the house gun was something that would work for both of us.

Massad's example, of a "large man" and his smaller wife might not be politically correct, but it is statistically the most likely direction of a hand-size mismatch.
