To those of you questioning the OP's mag capacity parameter:
1) Most BG's will flee if you have a gun, whether or not you have to shoot it, in which case capacity is moot.
2) If the BG is determined and aggressive, 6-8 shots may not be enough to stop the attack as all handguns are poor "stoppers" regardless of caliber or bullet used (now subtract the number of stress-induced misses from that 6-8 shots).
3) If there are multiple determined and aggressive BG's, how many shots to stop the attack, minus your stress-induced misses?
My minimum acceptable mag capacity is 12, my std is 15 plus I always carry at least 1 15rd reload. My best friend is retired LE and has never heard of a cop complaining about having too much ammo after a gunfight.
