Owners of the PDP Pro SD Full Size appreciate the factory-threaded barrel, which eliminates the need to have the barrel threaded aftermarket. The 5.1-inch barrel is seen as a good length for a full-size configuration, and the optics-ready slide pairs well with the platform for those building a suppressor-host setup.

The full-size frame provides a comfortable grip for most shooters and handles 9mm Luger recoil well. Some owners note that the longer barrel and full-size frame make concealed carry less practical than compact variants, positioning this model more toward home defense or range use. The PDP trigger is generally well received in this configuration.

At its price point, buyers compare it favorably to other threaded-barrel full-size striker pistols. The 10-round capacity is the most noted limitation for those in states without magazine capacity restrictions, where the expectation for a full-size pistol is typically higher. Build quality is consistently cited as a positive.
