Excellent thread
I'll be honest, I've never needed one at work or otherwise, but when I started to get smart about such things as banned magazines, I decided that "get them before there are no more" is a good policy.
Will I need one? I hope not, I'm still torn between 4 handguns as a carry choice, and I need to get my permit before I can do some empirical research!
It seems to me that many people switched to or chose outright a 9mm as a carry weapon due to the high capacity. The fact that many police departments and militaries still use the round, as well as the fact that they are not limited to 10+1, tells me that there has been some thought put into arming people with the maximum amount of rounds in a particular package. If you can legally carry a weapon for self-defense in according to state, local, and federal laws, then why can't you make the most of your firearm? The fact that militaries and government agencies are able to use the 9mm to its fullest potential (i.e. high-capacity mags) but normal citizens have to buy "preban" mags is what upsets many folks, I believe.
As far as recent stories, does anyone else recall a story about a South African security guard who had a gunfight during a robbery attempt, killed the attackers, then was involved in a second gunfight outside of the establishment, killing them as well? I seem to recall this as being in a major publication.
