Melee weapons
The melee weapon will replace the item found in your pistol slot. While only short range, they inflict more damage and can generally take care of the infected as they are close up.
If you are knocked down, you will use a single pistol instead of swinging your melee weapon.

Pistols
Pistol

When dual wielding you will be able to fire 30 rounds instead of 15.
Magnum
