A&G Grip Extenders are high impact polymer collars which slip over full size Glock magazines. When full sized Glock magazines are used with mini Glocks the A&G Grip Extension fill the gap between the bottom of the gun and the base of the magazine. This useful addition helps eliminate flinching and increases comfort and accuracy giving the shooter the grip and feel of its larger counterpart. Easily installed or removed, they work equally well with any full sized magazine, 10 round or Hi-Capacity. This model works with the G-20,21 magazines to use in the G-29 or 30 Glock pistols.
