How To Mount A RMRcc On A Glock 43?
To mount a RMRcc on a Glock 43 slide, it's best to mill the holes on a blank factory Glock 43 Slide (Non- MOS). This is way better option than buying adapter plates that end up mounting the optic too tall.
Most optic ready Glock 43 slides are milled for RMSc. Get the Brownell slide we recommended above for RMRcc
