Owners of the Walther PDP line, including the Pro SD Compact, generally report the pistol shoots flat and points naturally, with the ergonomics singled out as a strength of the PDP platform. The trigger draws consistent praise for a crisp, short reset compared to other striker-fired compacts.

For everyday carry or range use, the compact size and optics-ready slide are popular with owners running a red dot, and the threaded barrel makes it a common pick for suppressor use. Some shooters mention the tungsten gray and black two-tone finish shows wear differently than an all-black slide over time.

On value, the PDP Compact is seen as competitively priced against other major striker-fired compacts, and aftermarket holster and sight support has grown quickly given Walther's push into the optics-ready market. A few owners note the green recoil spring and other suppressor-oriented parts are a nice touch but add a bit to the price over a standard Compact model.
