I know that most people recommend L&M Precision ATOM installs but I have a question about the milling depth.  What is the depth of the cut in the top of the slide for the ATOM plate?  I am not trying to mill a slide myself, this is just a technical question in reference to miliing depth vs the firing pin channel.

Not sure how deep they go, but you can get away with pretty deep on Glock slides. We usually mill .1100" - .1200" deep on Glock slides for optic cuts.

For reference, it's not the depth that can be a problem with the firing pin safety pocket, it's the location that the pocket is machined. Your question implies that depending on the depth of cut it may be acceptable to cut into the firing pin safety pocket, which is incorrect. It is in no way acceptable.

Hope this helps!

Care to educate the masses a little more on that? What happens if you mill into the pocket but cover over it with a mounting plate?
Thanks in advance for any insight.

Read what I posted again.  I did not say firing pin safety pocket, I said firing pin channel.  I am talking about the depth of the cut above the firing pin channel.  I have seen shops who say up front that their optic cuts will go into the firing pin safety pocket and they say that they shorten or notch the firing pin safety to clrear the optic.  Anyone who cuts into any other existing internal cuts in the slide screwed up to begin with and cutting on the firing pin safety is not an answer to that problem.  I am taking about leaving an acceptable amount of material between two cuts, the optic cut on the top of the slide and the firing pin channel running directly below it.  From the factory Glock slides come with cuts where there is as little as 0.025-40" material left.  I am curious which slide has a deeper cut above the firing pin channel, an ATOM cut slide or a factory cut MOS slide.  I'm guessing they are both cut somewhere between 0.160-180" deep.

I don't know how deep ATOM cuts, but I don't go deeper than .120-.125" FWIW

You shouldn't mill into the firing pin safety pocket PERIOD. Anything done to make the gun function once you have made that mistake is completely unacceptable.
Any decent company will absolutely not mill into any internal pockets which can compromise the function and reliability of the firearm.
