Owners of the Walther PPK/S SD generally pick it over the standard PPK SD for the one-round advantage the PPK/S frame provides. In .32 ACP, that extra round matters to some and is a non-issue to others. The threaded barrel remains the defining feature, and owners who use it suppressed report a pleasant, quiet range experience given the mild caliber.

The PPK/S SD handles similarly to the classic PPK/S, which many owners appreciate. The grip is slightly longer than the PPK, giving a better purchase for larger hands. Fixed sights are workable but not adjustable, and owners wanting a more precise setup have to look at aftermarket options.

The .32 ACP chambering keeps this in a niche. Owners who want it for a suppressor host accept the caliber trade-off; those looking for a more practical defensive pistol sometimes second-guess the purchase. Reliability feedback is generally positive, with the platform's long history lending confidence in the basic design.
