Beretta produced special one-off pistols during its five-hundredth year, including the APX Falco. Working with Burris, the firm formed both the slide and red-dot housing from one steel block so the optic is integral rather than attached. Beretta patented the method and claims the two companies alone can currently achieve it following Burris work on electronics miniaturization, insulation and battery performance.

The Falco uses a skeletonized steel frame in diamond-like carbon instead of polymer, a magazine well cut into the frame, a lightweight ported slide with compensator, and a shorter pre-tensioned barrel. Gold-inlaid hand engraving uses falcon imagery, and the matching case is milled from aluminum with Alcantara lining made at the Pietro Beretta Atelier.
