I have issues with the dot as well, and I wear glasses. But some damage to my eyes are not corrected by them.
I found brightness levels to be a big factor on the starburst I saw. And it’s very common for new shooters with RDSs to turn up the brightness. I think it’s because we are coming from a sight based way of targeting and we naturally think now the red dot is replacing the sights. It really isn’t, it’s just there to give the shooter a reference, a shaded shaded area where the bullet should hit. Like they say, RDSs allows the shooter to be target focused. Everything else is a blur.
Now, I use non adjustable RMRs on my EDC. It has taken time to get use to the starburst, but now I do not even notice it. But it takes time and several draw strokes to do so. A one day course with a RDS instructor (actually two 4hr classes due to class size and China Flu) really helped, even after several hours of dry fire practice at home.
On dot sizes. To say a 6 or higher is inaccurate on a pistol is just….inaccurate. The dot size references the area covered by the dot at 100 yards. So a 6MOA covers 6” area at that distance. But at 50 yards, it’s a 3” area which is barely bigger than a post it note. At 25 yards, it’s 1.5” area. And at 12.5 yards, it’s .75”. So unless you are John Wick or a Tier One Operative, I doubt the area covered by the dot will harm your groups. But on the other hand, I have noticed smaller the dot, may cause problems due to the more movement the smaller dot shows and the shooters desire to have it perfectly placed. That great for target and hunting, but may slow the shooter down in any shooting situation. Even my hunting pistol carry a 3MOA dot on them. That’s about a post it note size dot at 100yards.
And the size of the window may be an issue as well. The “regular” RDSs are small already. And that means a small window to look thru. The newer micro sized ones are really small! Almost to the point that even without a dot showing, they make a good sight picture. I personally can’t use them, at least not for quick shooting situations. My RMRs are probably only a little bigger than the smaller Swampfoxs or Holosuns. I know the Swampfox and Holosuns are clearer, but not a durable.
I personally like the Holosun’s 8MOA circle. It’s on the 407 series. When they make it in green, might replace my RMRs. The circle really helps smooth out the starburst. And it seems to really help newer shooters, according to professional trainers that were pushing RDSs a few years ago. And I see why.
Hope you can find your path and get a good RDS for your EDC. The P365 is a great pistol in any flavor. I have a 365 and a homemade 365X. Will get an XL soon.
