I bought an optic for my 365XL finally but I wanted to go over it here a bit more about "why". Who knows. It might help some random person out there in the future some day.

Price wasn't a deciding factor for me at all. I am a firm believer in buying quality even if it's a few bucks more.

Originally I was intent on getting the RMRCC but today I stopped by a store and was able to handle a few optics with various dot sizes. In about 10 minutes I went from having one notion in my head to wiping that notion out fairly quickly.

Although I didn't compare exact models I got a good enough feel for what I was getting.

I decided on the Holosun 507k X2.

Why? For one it actually fits the footprint of my slide cut and will sit lower than an optic raised on a plate. It also has some very rudimentary rear notches on the optic itself that will allow some form of Co witness. It might not be much but it's certainly better than zero.

The 32 MOA ring I thought I would hate it. Turns out that is one of the best things about it. Boy was I wrong (and reserve the right to be wrong in the future as well). Compared to a 3 MOA dot it was night and day easier on the eyes to pick up. 32 MOA at 100 yards is 32 inches. At 50 it's 16 inches. At 25 it's 8 inches. And at 12 yards it's 4 inches.

I don't know about other people but 95% of your average shooters won't hold a 4 inch group at 12 yards with a pistol.

What's more is you have 3 reticle options. In the center of the circle there is a 2 MOA dot for fine tuning. You have the option of any of the three. Circle with the dot, circle with no dot, and dot only. For a learner options are good.

Also for tired eyes bigger did seem to be better. Tired eyes are about half of the reason why I am going with a dot anyway.

The illumination seemed very strong as in daylight bright which is also a big deal.

You also don't have to remove the optic to replace the battery. This is a big deal. I can carry a spare battery in my car or whatever so no big deal. Plus the cowitness with irons is still available at least somewhat. Probably not perfect but better than zero.

Overall I also think the construction was quite good. I was admittedly thinking it might be made of chineseium grade pot metal but what I handled would easily handle what I typically do during the day. Definitely not duty work unless you count typing as "duty".

Taking the time to put hands on some dots was really eye opening though. I'm glad I did and now I am more confident in my purchase.
