Trying to understand pistol optics better.

When red dot optic cuts started to become more popular and mainstream I feel like it was a flavor of: remove the rear sight and cover plate. That exposed a surface to which you mount a plate to than the optic of your choice.

Then I feel like manufactures left the rear sight on the slide, and the same thing occured.

In either of the above cases you'd need suppressor height sights in order to cowitness with the red dot, correct?

If the slide has a specific cut in it, say RMR, does that than sit low enough to cowitness with the factory sights?

On a glock, no. I dont think on any gun. I still find them useable.

You will likely need suppressor height sights to co-witness an RMR regardless of whether or not the gun has a factory cut or not. I'm sure a couple of newer designs can be used with very low profile optics and standard height sights, but I believe they are the exception.

There are some designs of sight and cut combo that allow stock sights but they’re rare. Do you already have one or you’re considering buying?

I do not currently own one. I was looking into the details before a potential purchase. I'm not even sure which gun I'd want to put one one.

On my MOS Glocks I need suppressor sites partially because of the mounting plate associated with the red dot. I have two Glocks cut for a specific red dot. The dot rides low enough in the slide that the standard sites work.

Nighthawk has come out with what they call an IOS system (Interchangeable Optics System). While expensive, it does seem to be an elegant solution to the issue. It appears to be limited to 1911/2011 platforms.

I’m a fairly resolute Gen 5 Glock fan so I think the Glock 45 MOS with FCD plate is a great setup. I think I prefer the PA/Holosun ACSS 507 dot over any other too.

I prefer backup sights to be in the very bottom of the window.

Co witness means to much stuff too look at (to busy).

I have solid black ameriglo suppressor sites on my guns with RMR's, I love that setup.
My smaller guns with RMRcc"s have a different setup due to the size of the optic.

It’s basically the same as the agency AOS for Glocks (I think they worked on it together).
