I have both the 6moa GR and the MRS GR, both Carry versions rather than this (the regular EPS will overhang your slide a little bit, but it also has a bigger window). Started with the 6 on my p10c and then grabbed an MRS when I saw it on a similar sale to this. I currently have the 6moa on my SP-01 and have the MRS on the p10 which is my EDC. Some will say it’s a gimmick, but I will say the solar adaptive brightness is convenient, automatically the brightest setting when I’m outside at the range or anything, and auto adjusts lower when it’s not as bright which keeps it from flaring out on me. I’ll also say I’ve been running just the outer circle because I find it quicker to acquire and it’s going to do the job at most reasonable self defense distances. If their center of mass is within the circle, you’re going to get good hits. I also have an astigmatism, but they’re well controlled with my glasses/contacts.

With this being your first optic, I think the bigger circle (with or without the center dot) would be beneficial, and as you become more proficient, you can switch to the center dot only down the road if you want. I will say, if you are going to run center dot only, I personally prefer 6moa on a pistol over 2moa, but that’s preference and both are usable.
