I’ve noticed that the Ruger RXM has a stainless steel tube/channel under the right side optics holes.  It prevents longer screws from being used and if I use the shortest ones (with Crimson Trace RAD micro), they quickly come loose.

Has anyone else noticed this issue?  Seems so weird unless I am supposed to use a longer screw on the left side only?

Pretty common with glocks honestly. I use one short screw, and 1 long screw.

That's the extractor depressor plunger in that channel of the slide. If you use too long of a screw, it will bind up the extractor from functioning properly. You will need one long screw & one shorter screw.

Thanks for the info, I am hoping that Vortex includes both sizes with their optics

loctite, all sight manufactures include long/short screws and you want to use the ones that match the taper for the sight your mounting

Take a look at the custom optic screws from Battle Werx.
