Shield Arms S15 Magazine 9mm for Glock 43X / 48 15rd Black

The S15 is Shield Arms' patented, flush-fitting 15 round magazine for the Glock 43X or Glock 48 pistols. The S15 is a steel magazine, and is the same measurements as the OEM Glock 10 round magazine, but holds an additional 5 rounds thanks to the increased durability of steel, allowing for a thinner magazine wall without sacrificing the integrity of the magazine.

It is recommended to use this magazine with the Shield Arms steel mag-catch to prevent premature wear on the factory Glock mag-catch.
