Shield Arms S15 Magazine for G43X/48

Shield Arms S15 Magazine is a patented, flush-fit 15-round steel magazine for the Glock 43X and 48. It has the same overall length as the factory Glock 10-round magazine but holds an additional 5 rounds without increasing the footprint.

Shield Arms achieved this increased capacity through a patent-pending magazine geometry that allows the rounds to stagger, delivering higher capacity without compromising reliability.

Required: Steel Mag Catch

The S15 magazine requires a steel magazine catch. The original Glock polymer mag catch must be replaced. The magazine is designed to function optimally with Shield Arms steel mag catches. Using the factory plastic catch or catches from other manufacturers may cause reliability issues.
