To be honest, I've only ever used this power before on people who were brainwashed into being hostile towards me. Since they were, of course, uncooperative, it was always resolved with a fight: I'd hit them with shots until they regained themselves.
For someone who isn't hostile, it shouldn't require anything special. Just the courage to stand in front of something vaguely gun-shaped, I suppose? I can fire it at a wall beforehand just to prove to you it doesn't fire real bullets. What it fires instead is more like... energy blasts comprised of my emotion, I suppose? So it can't cause tangible physical damage - it's more like an attempt to reach out to your psyche.
