Oh, I know how many weapons one could carry on oneself, concealed or not.
And yeah, as unreal-lifelike as dual pistols wielding is, that's one of the reasons I play The Secret World
As for the gun, I wasn't thinking Judge Dredd, as in you talking to your gun as the gun switching ammo for you. More like carrying mags with different ammo types. which you'd need to switch depending on the situation. And instead of having regular size bullets, as we know them today, have some sort of futuristic ammo: much smaller so you can carry a lot of it in one mag, but still does equal damage as today's bullets, or more. Kind of like an 80's cell phone vis a vis a blackberry. So, instead of having, say, a 10-mag of 9mm bullets, you can have that same mag carry 1000 pellets, or 1000 .009 mm "needles" that when they hit you explode, or when the penetrate they melt organs, whatever... something of that nature.
I'd still be happy if i get to dual wield .45s, though
