Hell no, I never even put a mag in until I have fixed a visual on target I'm gonna shoot at. In practice, only when the official tells me to make ready, or if alone, when I'm about to fire.
Other than that, my guns are kept hid in the basement gun cabinet behind two locked doors, and I don't keep ammo at the ready either.
