Before All Else Be Armed

The Shield Arms S15 magazine increases the capacity of your Glock 43X and Glock 48 handgun by 50% without increasing the size of the magazine. The S15 is an all steel magazine that has the same external dimensions as the Glock 43X and 48 magazines. However the interior geometry allows for the rounds to align in a double-stack manner increasing capacity by 50% from 10 rounds to 15 rounds. The high-lubricity finish helps the magazine drop-free from the magazine well whether loaded or unloaded for quick reloads. The impact-resistant base is easily removable if you want to replace it with a S15 extension. This magazine is the perfect upgrade for your 43X or 48 handgun.
