Owners of the Mauser MP40P gravitate toward it for its WWII-styled recreation in a rimfire pistol format. The 23+1 capacity makes for longer range sessions between reloads, and .22 LR keeps the cost per trigger pull very low. The optics-ready cut is a welcome addition for those who want to add a small red dot.

The 10-inch barrel gives the MP40P good velocity for a .22 pistol, and adjustable sights mean it can be dialed in reasonably well for accuracy at typical range distances. The black polymer grip is functional and durable, though a few owners note it lacks the texture they'd prefer for a firm hold.

Reliability with the MP40P follows the usual .22 semi-auto pattern: quality ammunition runs well, while dirty or cheap bulk loads cause occasional feeding issues. Aftermarket support is limited given it's a niche recreation design, but for buyers focused on fun and historical styling rather than a customizable platform, the MP40P delivers on that premise.
