The defining feature of the COA package is the Aimpoint COA red dot sight, factory-installed on the slide via the A-CUT mounting system. The COA is an ultra-compact reflex sight with a 3.5 MOA dot, powered by a CR2032 battery rated for over 50,000 hours (5+ years) of constant-on operation. It weighs 48 grams (1.7 oz), keeping the slide mass low enough that the porting can do its job effectively.

The A-CUT interface is what separates this from a standard optics-ready pistol with a red dot bolted on. Aimpoint developed the A-CUT mounting standard and launched it exclusively with Glock at SHOT Show 2025, initially available on the G19 Gen5, G45, G47, G43X, and G48. After a one-year exclusivity window, Aimpoint opened the interface to other manufacturers in 2026, signing over 30 companies including CZ, Springfield Armory, and Smith & Wesson. Instead of relying on screws alone, the A-CUT uses a front hook that tucks under a protrusion in the slide cut; the optic rotates down and locks in place with the rear iron sight assembly screwing in behind it. The result is a mechanically locked connection that handles the repeated G-forces of slide cycling without the loosening issues that plague screw-only mounts over high round counts.

The COA offers 12 brightness levels, four of which are NVG-compatible. It is sealed and submersible to 25 meters (80 feet), and Aimpoint rates it for 40,000 rounds of 9mm. CZ also fits co-witness iron sights identical to the P-09 Nocturne series, providing a backup sighting system that works with the COA mounted.

The CZ P-10 C Ported uses a large, single port near the muzzle to redirect propellant gas upward, counteracting muzzle rise during firing. This is the same approach CZ uses on the standalone P-10 C Ported model, which the German Bundeswehr selected as the P13 service pistol in its standard configuration.

The barrel itself is cold hammer forged and 10% heavier than the standard P-10 C barrel. The additional mass absorbs more energy during cycling, further reducing felt recoil. Combined with the porting, the P-10 C Ported COA shoots notably flatter than a standard compact 9mm, making it easier to track the Aimpoint COA's dot through recoil.

The extended cocking serrations on the upper slide surface provide additional grip area for manipulating the slide under stress. These serrations wrap further around the slide than standard P-10 models, useful when press-checking or clearing malfunctions with wet or gloved hands.

The international COA package upgrades the trigger with a duralumin blade, producing a smoother pull than the standard polymer P-10 trigger, and installs a duralumin magwell at the factory for faster reloads. The US market version will ship without the duralumin magwell and trigger blade to hit a more accessible price point, retaining the standard polymer trigger and grip. Pull weight across both versions measures 5.6 lbs (25 N) with a short 0.16-inch reset and 0.4-inch total travel.

Three magazines ship in the box regardless of market: 15, 17, and 19 rounds, giving shooters capacity options for different carry and competition requirements.

The grip uses CZ's DiFEND ergonomic method, developed using digital modeling, strain gauges, and aerospace-derived technology to optimize hand contact geometry. The fiberglass-reinforced polymer frame includes exchangeable grip panels and aggressive checkering. Metal parts receive CZ's "BoBox" deep nitriding treatment for corrosion and wear resistance.
