The PPX achieved its low price point partly by simplifying its barrel.

The PPX has a forged steel barrel that is attached to an MIM sleeve that locks into the frame and slide.

According to Walther Arms, the PPX design was tested for almost four years and over half a million rounds were used.

The Walther PPX has no other external manual safety mechanism, making it a simple and clean design but one that requires a holster that completely protects the trigger, particularly if the pistol is to be carried with a round in the chamber.

The PPX also has a standard integral polymer M1913 Picatinny rail for attaching lights or laser sights.

However, the PPX's frame lacks the interchangeable backstraps of other Walther designs.

However, its blocky appearance and tall slide, resulting in a high bore axis, generated criticism.

Walther decided to redesign the PPX with a simpler and improved design, with a better trigger, a smaller slide, and a few other minor changes.

The PPQ itself would ultimately be discontinued in 2021, in favor of the more advanced Walther PDP.

After the failure of the Creed and the PPX, Walther quit focusing efforts on making a budget self-defense handgun.

In addition to the slide and trigger mechanism being different, the takedown lever and magazine release have been slightly changed for the Creed.

The low-profile sights on both designs are slightly different, but both are made of steel.
