Beretta started selling frames with and without finger grooves in black, olive green, flat dark earth (FDE), and grey.

In July of that year, Beretta introduced three more designs, starting with flat dark earth variants of the Centurion and Compact models.

In addition to the changes to the slide and barrel, the frame is "wolf grey" colored and also has no finger grooves to better suit the needs of competition shooters.

The frame also features an extended magazine release and slide stop, as well as a green striker guide for a competition trigger.

[12] As of January 2024, Beretta still manufactures the first generation APX to fulfill existing contracts with military and police agencies, though only the A1 models are available on the civilian market.

Many of the improvements were taken directly from the competition-oriented APX Target, including the blacked-out rear sight, the red-dot standard slide, the lack of finger grooves on the frame and the competition striker and trigger assembly.

Slides and other parts will also interchange between A0 and A1 models, however in order to ensure proper function, the A0 needs to use its original recoil spring.

The APX A1 Tactical comes from the factory with three 21-round magazines, an olive-drab green frame, a threaded barrel and blacked-out suppressor height sights.

In 2024, Beretta introduced a flat dark earth version of the APX A1 Tactical with a tan slide and frame, albeit with a black interchangeable back strap.

The distance from the axis of the barrel to the top of the handgrip has been kept to a minimum of 21 mm (0.83 in) in order to reduce muzzle rise, which increases the ability to accurately fire quick follow-up shots.

APX A1s, on the other hand, use Beretta's "Aqua Tech Shield" finish that they first used on their shotguns, followed with a Bruniton coat on the slides.
