There's a one instance that sticks in my mind from VOY's "The Raven". After Seven's shielding has asserted itself, she passes two redshirts who fire at her.
The guard on the left manages to pull off hitting Seven at an odd angle, but most impressively he does it without actually pressing the fire button. He's holding the phaser with his thumb wrong in the wrong position, and just kinda jabs the phaser in her direction.
That's the kind of weapon you need in a firefight
