The Walther PPK is Sterling Archer's preferred and primary sidearm. First introduced in 1931, this weapon is famous as the weapon of choice for James Bond, the inspiration for Archer himself.

Archer is a crack shot with the Walther, frequently using it to shoot people he doesn't like, those who are annoying him, and occasionally himself. He has also been known to shoot people who enter rooms he is in after he has warned them to stay out ("Job Offer").
