This is a factory Glock magazine for the G27 subcompact — nine rounds of .40 S&W in the same proven polymer-over-steel construction that made Glock magazines the standard others are judged against. Factory Glock mags simply run: the hardened steel liner keeps feed lips true, the polymer shell shrugs off drops, and the spring and follower are tuned to the pistol. For a carry gun, spares should always be factory. Keep one loaded for backup, rotate them through practice, and your G27 stays as dependable as the day you bought it.
