Shield Arms S15 Combo Pack: (3) S15 Magazines and (1) Standard Steel Mag Catch for Glock 43X/48

The S15 magazine is a patent-pending, flush-fitting 15-round magazine for the Glock 43X and Glock 48. The S15 is a steel magazine, and is the same length as the OEM Glock 10 round magazine, but holds an additional 5 rounds.
