Suppose one of your hands and/or arms isn't working?

You need 2 to work a pump gun, one to work a semi-auto.

I take it you’ve fired 12 gauge 3 inch double ought shells 1 handed? I wouldn’t want to personally.

1 hand a shotgun? In a Hollywood action movie maybe.

If you are hurt that bad, you are not going to be using the auto either

No, you do not. The tactical shotgun courses I've taken teach how to operate the pump SG with one hand. I've shot many courses of fire with one hand -- loading/reloading, racking. It's slower but quite doable.

In a gunfight one may lose the use of a hand/arm. So, we learned how to operate from either side, strong or weak.

The pump is quite versatile, permitting one to load a slug on demand which may be tactically required (the "Alpha" system). But choose the right pump. Many are ill-suited for the "Alpha" system. (e.g. Benelli Nova pump requires the safety to be engaged to load). I trained with a Rem870. Others employed the Mossberg 590. Know the differences and train with both, because a gunfight is not the time/place learn about your weapon's operating system.
