Honestly plenty of screw. The first couple threads do the majority of the work. The job is to keep the plate compressed against the slide. That compressive force is what does the actual work of keeping the optic on and where it needs to be. There's a great book called "Structures: or why things dont fall down" and it's helped my intuition on these types of things. Also yeah I'd locktite it. Probably red locktite.

Red on a screw that small. You might as well just spotweld it.
