FAQ
Does A Glock 43X Slide Work With Polymer 80 PF9SS Frame?
Yes. These recommended slides work for Polymer 80 PF9SS frame.
Are Optic Cuts Worth It?
The factory Glock 43 slide works just fine to mount optics with compatible optic plates. We recommend CHPWS plates.
If you want to mount an optic without having to mill it or buy a Glock 43 MOS, an optic ready Glock slide is here for you.
In addition, these slides offer better aesthetics, serration patterns and overall feel.
How Long Is A Glock 43 Slide?
A Glock 43 slide measures 6.06 inches. Most aftermarket Glock slides will work with your existing holsters (Except for using a compensator)
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
