The trigger travel is 14 mm (0.55 in) long in the Anti-Stress mode, but the most of the length is slack and is similar in feel to a two-stage rifle trigger.
When the slide is racked completely to the rear upon loading, the trigger remains in the forward position for the first shot and the Anti-Stress mode is activated, where the striker is cocked but the trigger has the length of pull of the double-action mode. The original, first-generation P99 had a traditional Double-Action/Single-Action trigger with a decocker. A first-generation 9mm version, with a green polymer frame.
