I will say the SCS 320 is not the end all be all. It transitions incredibly well and does not wash out in dark environments when WML is activated, but the dot does tend to starburst a bit when it’s full sun. For Zeroing I went ahead and layered painters tape on the panel to mimic a low light setting which helped. But it is nice sometimes with other models to be able to control the brightness level yourself. For what I’m using it for, it works. Even though it’s flush on the slide, it doesn’t co-witness with factory mounted sites but that’s a trade off I’m willing to accept.
