The CAA Glock 17 Magazine Extension gives you an additional 10 rounds capacity. This is achieved by adding an extension to your original Glock magazine and replacing the original spring, making the Glock magazine longer. It utilises the existing magazine base plate.
This is a DIY installation and no gun-smithing is required.
