It's a placebo effect, for everything but the spread. Spread feels WAY lower, side by side vid comparison. Tapfiring is easier IMO.
Doesn't make sense, a placebo effect is a effect in a theory. You can't have a placebo effect on a visual or fictional weapons.
A placebo effect is a theory in sense that the human's mind would work with the items. Like giving a person a pill and telling them it is aspirin, but in reality it was sugar pill or something and they'll comment that it help get rid of that headache.
