The Shield Arms Magazine Extension design offers easy access floor plate to service or clean the magazine body without the need to remove the magazine extension from the magazine body. It boasts index cuts on the extension body to increase grip when coming out of a magazine pouch for added control. This is clearly a fast and easy way to gain additional capacity for your favorite Glock.
