FAQ

Does A Glock 43 Slide Work With Polymer 80 PF9SS Frame?

Yes.

Why Change Slide?

The factory Glock 43 slide works just fine, but 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, it's best to mill the holes on a blank factory G43 Slide (Non- MOS). This is way better option than buying adapter plates that end up mounting the optic too tall.
