It aint about fast. Its about eliminating error.

A lot depends on one’s vision. I need some correction to see even a red dot clearly, and definitely a regular front sight of any sort. Prisms have focusing oculars, so everything is sharp and clear just like a scope. I have a PA Prism on a Mini-14 that has a much larger FOV than the Mini P on my .410, but it cost over two times as much and is a lot heavier. Might try it later.
Another reason for an optic on a shotgun is for shooting slugs or other “alternative” ammo. My .410 put three Brenneke slugs under 2” at 50 yards with that Mini P and a Skeet tube.
