Expert Answer

The Polymer80 PF320 PTEX Handgun Grip Module is not compatible with the M17 because the M17 uses a manual safety, and these modules are not cut for a manual safety.

The Polymer80 PF320 PTEX Handgun Grip Module is designed for slides with a 4.7" or 5" barrel. The X-Compact comes with a 3.6" barrel so the frame will proceed past the length of your slide. You could potentially cut it down be flush with your slide. Or you can also use a module that was designed for the 3.6" barrel your X-Compact uses.
