Frequently Asked Questions
Will this plate work with both the Walther Q4 and Q5, or just one model?
This Shield Sights mounting plate is compatible with both the Walther Q4 and Q5 Steel Frame, as well as the standard Walther PPQ. All three models share the appropriate slide cut to accept this adapter plate, making it a versatile choice across the PPQ family of pistols.
Which red dot sights get a flush fit, and which have a slight overhang?
The Shield RMSc and SMSc footprints sit completely flush with this plate for the cleanest possible installation. The standard RMS, SMS, SMS2, and Jpoint sights are also fully compatible but will exhibit a slight width overhang due to their larger footprint. The RMSw will physically mount but may not achieve a complete weatherproof seal because the plate is narrower than the RMSw's gasket.
Do I need any special tools or gunsmithing to install this mount plate?
Installation is designed as a drop-in process using your Walther's existing factory slide cuts — no milling or professional gunsmithing is required. You will need the appropriate mounting screws (typically included or specified by Shield Sights) and a proper torque driver to secure both the plate and your optic. Always follow the torque specifications provided by Shield Sights to ensure a solid, zero-retaining fit.
