Checked my Jagerwerks RMR'd Glock. Thickness between the RMR base and ejector plunger hole is about .125. That equals 4 threads using RMR standard 6-32 screws. On the P10, the .063" thickness results in 2 threads of engagement. 6-32 major diameter is .138". The rule of thumb is to have the same depth of engagement as the major diameter, so even the Glock comes up short. Now according to an engineering calculator, minium required thread depth comes out to .068" or just over 2 threads. So threads over the striker tunnel is alittle short but still probably okay since the pockets and rmr body take the recoil forces. Biggest concern is vibration backing out the screw, but that's what loctite is for. The other screw is full depth and the pocket has more surface than a standard rear sight, so racking it off objects should not damage it. Glock MOS mounting plates are .100" thick, and the plates have been reported to break before the optic.
