Most powerfull handgun in mw3 :
- n°1 : Desert Eagle (2 bullets at short range)
- n°2 : .44 Magnum (2/3 bullets at short range)
Deagle is really strange to use on single : you have to kill a lot of people before to get it in akimbo
So i recommand you the .44 magnum, most easy to use on single, really powerfull, same at long range, it's really a great gun !!!
I've use the .44 without sleight of hand, no problemo, it's my best choice !!!
I hope it will help you
NB : P99 is a bad choice for akimbo, use it with silencer or extra mag
