The Shield Arms +5/4 Magazine Extension increases capacity on factory Glock 19 and Glock 23 magazines without compromising reliability or concealment. This extension adds 5 rounds to 9mm magazines (19 rounds total with a standard 15-round G19 mag) and 4 rounds to .40 S&W magazines (17 rounds total with a standard 13-round G23 mag). Designed for shooters who want more capacity for competition, duty, or home defense without moving to a full-size frame.
Machined from aluminum with a durable Cerakote Mud finish that resists wear and corrosion. The extension installs with basic hand tools and includes a replacement magazine spring and baseplate. No permanent modification to the magazine is required. The extended profile maintains a flush fit with the grip of a Glock 17/22, offering a compromise between capacity and concealability.
