Why is eveyone raggin' on the pistol, saying it's too powerful and so forth? It takes ABOUT 4 shots to the head to take someone down with it. Now for all of you who say that isin't realistic and that it should take more shots: the Halo pistol is a 12.7mm weapon right? Well I'm not sure, but I don't think I could survive a SINGLE shot to the head with a real world 9mm. So yeah you're right it isin't realistic, it should take only one maybe two shots to bring a Spartan down because those rounds are semi-armour piercing, high explosive, BIGGER rounds. And they are NOT trashing the pistol.
