M629

The Smith & Wesson M629 is a .44 MAG revolver. I have no clue about the range or damage though its .44 Mag so it might pack a punch. It probably has good range and spread, though I'm not sure about this.

Pros
I guess you would move quick and dodge bullets easier with this gun equipped, because it doesn't slow you down as much since it's a pistol.

Cons
You can probably Dual Wield it(?).
