To find out when your Glock was made, you can check the serial number located on the frame of the pistol. Glock uses a coding system where the first two digits indicate the year of manufacture. For example, a serial number starting with "AC" would suggest it was made in 2001. Additionally, you can contact Glock customer service or visit their website, where you can input your serial number for more detailed information.
There is a large serial number database on Glocktalk.com. Some books published on Glocks are available that also contain data.
