Another thought. One of the beauties of the 45ACP is that it is still very lethal with cheap 230gr. ball ammo. I carry Hornady Critical Defense ammo in it but I doubt I have more then a couple hundred rounds of it at any point and time. I can switch to ball and still be well armed.

My 9mm carry gun is a H&K P7 loaded with Hornady Critical Duty ammo. I might have 4-5 boxes on hand. If I run out I have 100,000 target loads that candidly I might be better off throwing at a bad guy ....

The 40 is probably in the middle? How does it fair with target loads in a pinch?

I think NATO 9mm Ball loaded by Winchester is actually +P, am I wrong on that as well?
