ETS Group
The ETS Group GLK429 is an extended-capacity polymer magazine purpose-built for the Glock 42 in .380 ACP. If you carry or shoot a Glock 42 for self-defense or plinking and want more rounds on tap without changing platforms, this 9-round magazine trades the factory's 6-round capacity for extra shots in the same slim profile. The clear polymer body lets you verify your round count at a glance, and ETS's reputation for reliable, durable magazines means you get function without the premium price of OEM Glock mags.
Extended magazines for compact .380 pistols sit in an odd middle ground: they add weight and slightly increase the grip footprint, but nine rounds versus six is a meaningful upgrade for defensive applications or range work. The GLK429 bridges that gap with reinforced feed lips and proven reliability across thousands of rounds. Whether you're building a backup magazine locker or you just want a spare that holds more, this is the kind of accessory that pays for itself in range trips.
ETS Group polymer magazines have earned trust in the tactical and civilian markets for consistent function across various firearm designs. The clear construction is practical too—no guessing whether you're loaded up before you head to the range or into the field.
