This isn't correct. The real world accuracy record of people with handguns, even supposedly trained professionals like police, is pretty dismal. Sight radius is very significant, by something like a multiplier of several times. This is why all military organizations and all special police forces use long guns if they can. Magazine capacity is significant, but slight by comparison to handgun vs. rifle, especially in the context of mass shooting and terrorism. Magazine capacity is most significant when it comes to gun vs. gun.
