What iron sight heights provide a lower 1/3 co-witness for a Glock slide milled for an RMR?
I have a ZEV slide that is milled for an RMR which also has some suppressor height sights and after installing an RMR they are too high for my liking.
For the OP, do look at Ameriglo’s offerings which has several sight sets depending on personal-preference; optic; slide cut; and other factors. Ameriglo is also coming out with its “Haven” product-line which also includes iron sights with its red-dot electronic sight (reviews are just now starting to show up on Youtube).
I likely also will be researching which electronic sight, along with exactly which backup iron sights to get if/when I ever get around to it. But do have a look at Ameriglo’s website which seems to have the best selection/variety:

I like Ameriglos sights and I have their I-dot sets on my other Glocks, but I cant find any information on what sight heights will give me a lower 1/3 co witness. Ameriglos site doesn’t specify and it just shows three sight heights, XL, 2XL, and 3XL.
Also, is there an industry standard in regards to how low the RMR cut is on the slide?
I am using AmeriGlo GL-511 on my Zev Trilo RMR cut slide. They are $67.50 @ Primary Arms. They give me a lower 1/3 co-witness.

The sizes are listed for every set. You may have to do some math because if you’re not using a MOS, there is no industry standard for milling the slide. On a side note, I’m of the opinion that cowitnessing sights on a pistol is meaningless. As long as they are high enough to be seen in the window that’s good enough. The only time you should even be acknowledging your irons is in the case of your dot going down. If you’re using both irons and dot in combination, you’re slowing yourself down. Just focus on the dot and the target, keep the irons out of the equation. They are a “backup”.
Focus on the target and superimpose the dot.
Correct. I should have worded it better. I just meant that your backup irons shouldn’t even be part of the equation.
Agreed, when I first moved to an RMR I removed my sights and ran the gun w/o sights for a while before installing my taller Ameriglos for backup. I think for my next setup I’m going to try the rear sight forward of the optic.
I think that method would serve many well. You would think as much as the term “backup iron sights” is used on this site, that people would understand what it means.
Well when you forget to turn your optic on and get to the first shooting stage of your 5k run and gun, those backup sights came in handy for hitting the 50 yard torso target. Note to self, check when charging pistol at the start, turn on optic.
So I ended up installing the ZEV sealing gasket plate and the Ameriglo GL-411 sights but they still seem just a bit too high, it seems slightly higher that lower 1/3, or maybe it’s that I just don’t have any experience with this setup.
I haven’t even been to the range yet to zero this red dot sight, but when looking through the sight what should the sight picture look like? If I take the slide off of the gun and look through it while focusing on a miscellaneous object in my house while trying to keep the red dot centered in the upper 2/3 of the sight is the front iron sight supposed to be above the rear iron sight? I have also noticed that the slight tint of the lens makes it more difficult to focus on objects.
When its all said and done with the red dot zeroed independently of the irons what is the typical sight picture?
