In CQB? All the time, and its usually my primary.

Outside, with a sniper rifle? Only when shit hits the fan and somehow the enemy gets too close.

When using an automatic as a primary? Only if the gun somehow stops working or I'm out of ammo. There's some exceptions, on well built fields, I often use it inside buildings, but in purely woodlands areas, I often don't even carry one anymore unless the field is very large and I can't access the respawn easily, then its good to have a backup on you just in case.
