Yeah, the gun isn't necessarily made less accurate with a shorter barrel. I've seen people ring coffee cans at 100 yards with every round from an officer's model 1911 clone. But the shorter sight radius makes it harder to use that accuracy potential without practice, and I need practice. And I need a 6 o'clock hold for a sight picture.
And I think lawsuits over IP are pathetic. Make a better product, don't try to hire better lawyers. Plus, I don't see what's supposed to be patentable about the mag in the first place.
