The Walther PDP Full Size pistol in 9mm Luger with a 4.5-inch barrel and 10-round capacity (brand part no. 2858126) extends the standard PDP Full Size with a longer barrel for a longer sight radius and slightly increased velocity. Walther Arms pairs a steel slide with a polymer frame, and SuperTerrain slide serrations combine with the Performance Duty Trigger for a crisp, repeatable pull. The pistol weighs 22.3 ounces unloaded, features three automatic safeties, and ships with two 10-round magazines and 3-dot white sights. Among full-size semi-auto handguns, this longer-barreled PDP configuration favors shooters who want maximum sight radius in a compliant-capacity platform.
