Glock 17/19/22/23 – Magazine Extension – +5 Capacity


PLEASE DOUBLE CHECK DETAILS, FITMENT, AND LOCAL MAGAZINE LAWS BEFORE PURCHASE.

The Backup Tactical +5 Magazine Extension adds capacity to compatible Glock 17, 19, 22, and 23 magazines and includes an extra power spring. It is built for shooters who want more rounds on compatible factory-pattern magazines without swapping to an entirely different magazine body.

Available options are organized below under variants. This is a capacity-changing magazine extension, so verify your exact magazine body and local laws before ordering. Extra rounds are useful. Wrong-fit parts are just expensive drawer decorations.

What It Does

This extension increases capacity on compatible Glock magazines and provides the spring support needed for the longer stack. It is useful for range setups, competition-style use, PCC setups that run compatible Glock magazines, and anyone who wants more rounds without turning their reload plan into a full-time job.

Why It’s Worth It

This is a straightforward way to add capacity and reload grip surface to compatible Glock-pattern magazines. The included extra power spring matters because extended capacity needs proper spring support, not wishful thinking and a lucky range trip.
