Walther PDP (Polymer) Plus 4 Magazine Extension by Henning Group
Our extended base pads are legal for USPSA Limited and Open competitions. Attached to the factory magazines they extend the magazine to 141.25mm length (5.56"). Whether you want to be competitive or not, these pads will extend the capacity of your Walther PDP magazines.
Our extensions are EASY to take on and off with our spring-loaded steel detent. It locks the extension onto the magazine tube very tight and securely.
Just adding this magazine extension to the factory Walther PDP magazine, it will increase the capacity from 18 to 22 rounds, but the factory spring is recommended to be replaced with an aftermarket follower kit. You can use the Rune aftermarket follower kit to get 23 +1. You can use the MBX aftermarket follower kit to get 24 +1.
We have TWO models: one that works for the polymer PDP models and a brand new (January 2024) for the PDP Steel.
MBX "Ultra Max" Spring & Follower
*Note This Product will not lock slide back on last round fired

My experience
These are advertised as a +4, but I can load 24 rounds into mine (with a little give at the top to seat the mag) using MBX spring+follower and a standard Canik 18 round tube. Very easy to install.
