An enhanced version of the P1, the P1 Ultra has a scalloped slide and exposed barrel to give it a new attitude. It also come with a slide-adjustable rear sight and fiber optic front sight. P1 is a SA/DA model with a shorter barrel and slide. This feature is mainly appreciated at concealed carrying for personal defense. The accuracy and shooting action remains unchanged comparing to the full-sized models despite the shortened barrel. The frame is fitted with universal tactical Picatinny rail MIL-STD-1913.
