Since the SAFE Act limits rounds in a magazine to 7 unless you are at a range (even then, you are limited to 10), would you rather use a .45 or 9mm for personal defense? I am not trying to beat a dead horse and I know there is a large debate between the two, but I am not sure this topic has been touched on in this specific way.
I understand the lower recoil of the 9mm would allow for faster follow-up shots and the .45 has more punch to it, but you will be carrying the same amount of ammo per magazine with either weapon. Faster follow-up shots of the 9mm will burn through those 7 rounds faster, making you have to change mags sooner. Since you are limited to carrying the same number of rounds per mag, doesn't it make more sense to carry the round that packs more of a punch?
