The PDP Pro SD Full Size is Walther's dedicated suppressor-host configuration, and owners who build it around a can tend to be satisfied with the platform. The 5.1-inch threaded barrel is a natural pairing, and the PDP trigger gets consistent praise as one of the better factory striker-fired triggers available without modification.

The FDE finish draws attention in person, and the two-tone look with the black frame is a point of pride for most owners. Ergonomics on the full-size PDP frame are well-regarded, with the grip texture and beaver tail receiving particular mention for control during extended sessions.

The 10+1 capacity is a limitation for some buyers who compare it against higher-capacity competitors in the same price bracket. The PDP Pro SD also sits at a premium over the standard PDP, and buyers occasionally debate whether the threaded barrel and SD designation alone justify the cost difference.
