Does an RMR fit a Glock 43X MOS?

Short answer: not a full-size RMR Type 2, unless the plate title says 43X/48 MOS to RMR. 43X MOS and 48 MOS use a smaller cut than 19/17 MOS. The Trijicon micro for that cut is RMRcc (3.25 or 6.5 MOA) plus a 43X/48 MOS-to-RMRcc plate. A 19 MOS-to-RMR plate will not bolt on. We sell parts, not pistols.
Holosun 407K / 507K / EPS Carry use K plates (C&H, Night Fision). We list those plates. Mepro MPO-DS is RMS-C. Stacking a full-size RMR Type 2 on 43X MOS is a tall, uncommon plate — only if the title says 43X/48 MOS to RMR. Non-MOS 43X has no MOS holes. 43 slim is not 43X MOS.

Questions
Does an RMR Type 2 fit a Glock 43X MOS?
Not on a 19 MOS plate. 43X/48 MOS is a smaller cut. Use RMRcc plus a 43X/48 MOS-to-RMRcc plate, unless the plate title says 43X/48 MOS to RMR.
Will a 19 MOS plate bolt onto a 43X MOS?
No. Different hole pattern. Use a plate that says 43X or 48 MOS.
Does a non-MOS 43X take RMRcc?
No. Non-MOS has no MOS holes. 43 slim is not 43X MOS.
