Walther WMP owners frequently cite the optic-ready cut as a highlight, treating this as a serious rimfire pistol rather than a novelty. The .22 WMR chambering gets attention from owners who want more energy than standard .22 LR without stepping up to centerfire calibers.

The threaded barrel on the SD variant is popular, and owners note the WMP pairs well with suppressors for a quiet range experience. Adjustable sights are well-regarded for a pistol in this class, though a few owners find the factory zero needs adjustment out of the box.

Trigger feel splits opinions: some owners appreciate the crisp pull for a polymer-framed pistol, while others find it heavier than expected for a rimfire. Reliability with .22 WMR ammunition is generally good, though some ammo brands cycle more cleanly than others, which is a common characteristic of the caliber.
