I'm starting to get curious as to whether a red dot on a pistol is right for me. I'm giving serious thought to a Sig P365XL with a red dot of some sort as the successor to my Walther PPS (because who doesn't want more magazine capacity in a small slim package), but I'm concerned that it may be problematic due to my having astigmatism. Is it something that could work, or given my experience using red dots on rifles (reticle is an oblong starry mess), is it something that I would be best off just skipping it, saving the cost of the optic and devoting that to ammo instead?
 
My experience with red dots on both pistols and rifles is try it first. I have some I see an 8 instead of a dot, some look like a starburst. and others work great. I have better luck with the tube style than the micro dots. one of the ones I was going to get ride of my granddaughter took and is using says it perfectly clear. See has good 15 year old eyes.
 
I would try it before you buy. I think the small ones with the light being shot at upright glass may be an issue for you. My buddies with that issue are OK with the tube types (sometimes).

Will be curious to see how the new Leopold micro that replaces the rear Glock/S&W does for people in the OP's situation. I'm not sure how that one is designed.
 
Take 12bravo20's advice and turn the brightness down as much as you can. Also, don't buy a cheap Red Dot, or Green Dot. You do get what you pay for and the cheap ones will probably have a 6 moa sized dot. That's fine if you are only looking for "minute of washing machine" accuracy. The better ones have a 2moa or smaller dot and some have a selector switch to choose different reticles. Personally I like the type that has a cross with the center open or the hollow circle type. I also have an astigmatism, but not severe,.
 
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.

I'll have to take a look at some pistol RDS. I currently run a Trijicon MRO on my rifle and keep the brightness on setting 3 or 4 of 8 and even with contacts or glasses, it's not a crisp dot. With glasses it's a star, and with contacts, it's more of a figure 8. I've also got an ACOG that I tend to prefer for the crisper reticle picture, though I have resorted to running electrical tape over top of the fiber optic to tame the brightness.
 
My astigmatism probably isn't as bad as some others here. but I had a pair of glasses made specifically for shooting. I traded some clarity at distance for a focus point exactly where the sights are when using handguns. All the correction is in a single plane of focus. the entire lens, so it doesn't matter if I'm looking out the edge or the center. The correction on the non dominant eye isn't as strong so I can see the target better. For me. it completely solved the RDS (and open sights) issue. it's as clear of a point as I could wish for and the front sight in the other pistols is as sharp as if I was 18 again.

Where are these dang bionic eyes Steve Austin and Jamie Summers had that TV promised us by now anyway?
 
I didn't even know I had an astigmatism until I put a dot on my EDC firearm. At first I thought my dot was defective, until I noticed I only saw the distortion with my right eye. I switched the reticle on my sight to a 36(?) MOA circle with a dot on the middle. That helped significantly. I also had my optometrist put a stronger astigmatism correction in my regular glasses.

If it’s a Holosun, it’s their 32MOA circle with a 2MOA dot. It allows you to use either the dot only, circle only, or both. Great RDS!

Yeah, I found out I was cross eye dominate. So I shoot lefty and throw my head over so my right eye sees a clear dot. LOL After a shoulder replace and a hip surgery, I joked with my surgeon and said she is going to have to work on my neck next. She said why don’t I just learn to shoot right handed. Told her I had too many left handed holsters and gear for that! LOL.

Turn your brightness down as much as you can and still see the dot
This works in low light for me,bright light I just deal with the blob. When I had a RDS on my AR and wanted a defined dot in bright light,I would flip up the rear appeture sight and look threw that at the RDS.
 
Without glasses (after cataract surgery) I get an "asterisk" shape.
But, it's not large enough to obscure targets at pistol ranges.
(And I may have more than some fair share of 3+ MOA dot training time, too.)
Now, with glasses, the dot get nice and round and well-behaved.

At any range beyond pistol, I'm totally sold on "circle dot" sights.

But, that's me; YMMV
 
Have the same problem when I shoot my red dots I wear "cheaters" at the right magnification for distance and the dot pretty much clears up.
 
Well, after having tried a few different options, I've come to the conclusion that a red dot for my handguns just isn't as viable as standard iron sights. With the few that I tried, the dot was distorted by my jacked up eyes enough to make accuracy suffer compared to iron sights, and I was also a bit slower cycling between multiple targets compared to iron sights because I would have to try and refocus my eyes to minimize the blurring of the dot. So, I'll just resign myself to the fact that I'll never be cool enough to run a dot sight on a pistol like the tacticool crowd.
