The date code for a Walther P22 can typically be found on the slide or frame of the firearm. It consists of a letter followed by a number, indicating the year of manufacture. For example, a letter "A" followed by "01" would indicate the gun was made in 2001. To accurately determine the specific year of your P22, refer to the manufacturer's date code chart or consult Walther's customer service.
