UMP45 Vs. UMP9

So you’re preparing your arms locker for the undead invasion and your trying to decide whether to go with the .45 ACP or the 9mm UMP.

My recomendation is to shoot both and see if the .45ACP round has too much kick over the 9mm for you.  If you can handle the extra thump from the .45ACP, it is going to provide you that extra bit of insurance when you’re trying to put bullets through skulls.
