Before you buy anything:
The F-Series uses the "New Style" (Gen 2) optics cut. When ordering your free plate from Walther (or buying an aftermarket one), ensure it has the recoil lugs.
A common failure point on RMR mounts for the PDP is relying solely on the screws for shear strength. The F-Series slide rack is lighter, but the recoil impulse remains snappy are non-negotiable.
Torque Specs for F-Series Optics:
- Plate to Slide: 15-18 in-lbs (Blue Loctite recommended).
- Optic to Plate: 12-15 in-lbs.
- Note: Over-torquing on the F-Series slide can lead to screw shearing due to the shallow thread depth on the optics pocket.
