The Walther P99 QA (Quick Action) is the quasi-double-action variant of the P99, featuring a consistent trigger pull on every shot that is lighter than a traditional DA but heavier than a SA. The QA trigger has a short take-up with a consistent pull of approximately 6.5 lb on every shot, similar to the striker-fired triggers that would become standard in the following decade. Predecessor to the PPQ trigger system.
