The Shield Arms S15 +5 magazine extension gives you the extra capacity you need without making major sacrifices. Built from precision-machined billet 6061 aluminum and finished with Type II anodizing, this extension is made to handle regular use at the range or in the field.
Starting with a Shield Arms S15 magazine already gives you a serious upgrade over factory Glock magazines. Adding this extension pushes your total capacity to 20 rounds, which makes a real difference during competition, training sessions, or when you want extra rounds on hand without carrying multiple magazines. The extra weight also helps your magazines drop cleanly and consistently when you reload.
The standout feature here is the easy-access floor plate. You can clean the spring and follower without having to remove the extension from the magazine body, which saves time when you're breaking things down for maintenance. The extension also has index cuts molded into the body, giving you better grip when drawing the magazine from your pouch.
This extension fits Shield Arms S15 magazines only. It comes with a 12-coil plus power spring included, ready to go. The extension fits most aftermarket flared magazine wells, so if you're running a magwell on your Glock 43X or 48, you should be fine. Like all Shield Arms products, it's backed by their lifetime warranty and Spring for Life guarantee.
The extension itself is designed for Shield Arms S15 magazines, not OEM Glock magazines. You'll need S15 magazines to use this extension. Once installed on an S15 magazine, it's fully compatible with Glock 43X and 48 pistols.
While the extension will function with the factory polymer catch, Shield Arms recommends using their steel magazine catch with S15 magazines. The steel body of S15 mags can wear the polymer catch faster over time, so upgrading to steel provides better longevity and durability.
Yes, that's one of the main design features of this extension. The easy-access floor plate allows you to quickly get to the spring and follower without having to remove the extension from the magazine body itself, making maintenance and cleaning much faster.
The extension comes with a 12-coil plus power spring ready to install. You don't need to purchase additional springs separately to get the extension working on your S15 magazine.
