will this work on a walther pdp

Manufacturer Answer
A
Answered by Swampfox Optics, Manufacturer from CO, United States, on September 02, 2026

Yes, provided the pistol is equipped with the correct RMR-pattern optic plate for its specific PDP slide version. The Kraken attaches to its included RMR adapter plate, which then mounts to the pistol’s RMR-pattern plate. Confirm which PDP optic-cut generation you have before selecting the plate.

Will this fit a gen 6 Glock 45?

Manufacturer Answer
A
Answered by Swampfox Optics, Manufacturer from CO, United States, on June 24, 2026

Yes, but not directly. The Kraken includes a legacy Glock MOS adapter plate and an RMR adapter plate. For a Gen 6 Glock 45, you will need to use the included Kraken RMR plate in combination with the Glock Gen 6 RMR adapter plate.

We are currently working on a dedicated Gen 6 adapter plate solution. Be sure to sign up for email notifications and keep an eye on your inbox for updates when it launches.
