Unlikely, in the show they routinely missed targets
You never know, they still might. Especially if it turns out the main advantage of hand phasers is that it doesn't actually have to be pointed at its target to hit it; some sort of auto-tracking feature in Phaser-II allows the phased-array emitter (which is actually several emitters packed into a torroid) to steer the beam a few degrees off boresight and guarantee a hit.
