Staccato (STI) Staccato P DPO 9mm 2011, 4.15 in Bull Barrel, Dawson RMR DPO Plate, Fiber-Optic Front, Picatinny Rail, 17+1
This Staccato (STI) Staccato P DPO in 9mm pairs the 4.15-inch bushingless bull barrel of the P with the Dawson Precision Optics system, including an installed RMR-footprint DPO plate. It carries transitional STI/Staccato factory markings from the rebranding period and a small U.S.-flag engraving on the frame. The pistol is in very good condition with an excellent bore and comes with three 17-round magazines, a factory soft case, paperwork, and a Safariland holster.
The DPO setup places a black rear sight on the optics plate and a green fiber-optic front sight on the slide, offering a clean iron-sight picture while accommodating the RMR footprint. A full-length Picatinny accessory rail runs the dustcover, and the slide features front and rear cocking serrations.
Controls include an ambidextrous thumb safety and a beavertail grip safety with a memory pad. The 2011 polymer grip is textured and features a flared magwell for streamlined reloads. A skeletonized trigger and skeletonized commander-style hammer round out the single-action-only fire control system.
Notable factory and plate markings highlight its transitional lineage: the slide is marked "STACCATO ★ P," the frame is marked "20★11°," the dustcover underside is marked "STI INTERNATIONAL - GEORGETOWN, TX USA," and the Dawson DPO plate is marked "011-220 DPO PAT." A small U.S.-flag engraving appears on the left side of the frame above the trigger.
