Lower the "iron sights" on hand cannons to be closer to the barrel of the gun.
So I just got Lumina and I'm loving everything except the "iron sights".
They seem to be quite high up above the gun like on Thorn. I personally like to aim with the barrel of the gun and when the sights are so high up it messes up my aim. Then I'm trying to place the already tough to see dot on my enemies instead of using the gun itself to aim like you would on a regular gun.
If they were closer to the barrel of the gun it would be much more useful and more like a regular gun.
Just a thought.
