The Shield Sights Mount Plate for the Walther Q4/Q5 PPQ (brand part no. MNT-PPQ-SMS-RMS) lets you co-witness a reflex sight on a Q4 or Q5 pistol using the RMS, RMSc, or SMS footprint. Made by Shield Sights, the plate sits flush with the compact RMSc and SMSc housings for a clean fit, and it also accepts the standard RMS, SMS, SMS2, and Jpoint sights, though those sit with a slight width overhang since the plate is narrower than their full footprint. The RMSw will physically fit as well, but its wider gasket may not seal flush against this plate.
