30 rounders?

Why?

Why?

Because if six rounds isn't enough, carry a spare magazine. If that's insufficient, IMO, you are no longer in a defensive position, you are in a war. If you are in a war, you should have brought an assault weapon, not a pistol.

Anyway, over the years, I have found that a pistol usually works better if you use a magazine of the capacity specified by the designer and supplied by the manufacturer.
