Should put this in infiltrator topic since were the ones using it mostly in CQC. To put it simple it hit like a truck if you "hit" your target. Im pretty sure it 2 shot in the head to kill and 4 in the body to kill. Can't really remember it but hip fire is hard to master on that gun.
Pistols are usable by every class so I didn't see a point in putting it in a class specific subforum.
Yes, it hits like a truck. I equip it as secondary in all my loadouts, however I often forget to use it. I have killed several enemies very quickly with it. It just takes careful aimed fire, like most NC weps.
