When It comes to weapons and such, I think it would be interesting, fun and more realistic to present the weapons in the following fashion.

When walking, creeping, crawling and running the weapon in your hands will seem to float around. If you pull the trigger it will quickly attempt to line up with the estimated center of your screen and fire.

When you, for example are running around in a town, and find a German squad with it's back turned moving down the street, you can hold a 'Aiming' button much like in Goldeneye for N64, or Perfect Dark. When you do so, You bring the weapon up to your shoulder and cheek, and you actually aim down the iron sights, Or scope if equiped.

This way, you have better control over the weapon, then wildly aiming a weapon from your way lower right hip.

Plus in reality, if you want to hit something with a Pistol, rifle, submachinegun, Panzerfaust Etc, You will aim down it's iron sights. This is why you see those sniper army guys you see in them movies always look down their scopes to hit a target, instead of hiping the weapon and shooting a 2 and a half inch group at a thousand yards..
