Benefits of a Pistol Caliber Carbine?

[echo5whiskey]

I'll add that if someone in your house is willing to use a gun but isn't interested enough in shooting to learn a handgun well they'll probably enjoy training (fun + learning + easy hits = familiarity and confidence) with a 9mm carbine.

The same person will not enjoy a rifle or shotgun near as much and wont want to shoot / learn.

This is an excellent point.

That is what initially drew me to them. My wife is very small framed; and, while she's an excellent shot with a pistol, she shoots my AR better. The issue is that it's just too long for her to handle comfortably while moving around. I thought it would be a good compromise for her, and maybe make a good truck gun.
