Yeah, bigger caliber for what ? Hit two target with one bullet instead of one target ? Uselless for law enforcement.
9mm Gold Dot it's the perfet one for my job, when I have to stop a car, I know that I can shoot at it easily with the HK UMP9 at 90-100 meters without kill the driver, 'cause yes, here in France when a policeman or a soldier like me use his weapon against a target (I said in France, not on a war theatre), he shoot at it not for kill the target but to neutralize it. It's not the same thing. So .40SW for example, it's useless for us.
