I've messed with an ACRO (300 rds) and a Gen 2 RM06 (3,000 rds) on my G19.5 MOS. Per this thread, I went back to Ameriglo bold-type tritium irons in November (https://pistol-forum.com/showthread....like-it-better).
I've not been doing much with the gun other than carrying it. I have a class coming up in about a week and so I shot about 100rds yesterday and another 100 today confirming sights and POI 0-25yds. Everything is just like I hoped it would be, so we're good there.
I have very good vision and the main advantage I saw to the dot was the ability to hit at distance (50yds +) compared to irons. Not that it's my everyday, but it sometimes gave me great peace of mind to know that I effectively had a PDW concealed on my person at all times. Going back to irons, I have to work much harder past 25yds to achieve good hits, so I occasionally entertain the idea of an RDS again.
Here are my big hangups:
1. Brightness. Even if you adjust the RMR before holstering, it eventually "forgets" where you set it to and goes back to auto-leveling. Furthermore, It takes a second to auto-level. In practice, I found multiple times when I would present the pistol I'd been carrying all day when undressing at the end of the day or around the house and the dot would not be visible.
2. Use in low light with WML. See above, but exacerbated by being washed out by the WML.
3. Battery Life/re-confirming zero after changing batteries
Is there good tech on the market yet to overcome these issues or are we still waiting? I suppose in some ways the ACRO could overcome #1 and #3 if I just ran it on max brightness, but then I'd be changing batteries every month.
I can see where some of these issues might be different for LEO's who in some ways can plan their need for the gun better than I can, check before going into a house, etc. For me as a concealed civilian, the gun has to stay concealed until I need it and when I need it, I need it to be ready 100% of the time. To me, the above issues make it not ready 100% of the time.
