ETS GLK429 9-Round Extended Magazine 380 ACP Glock 42 Clear Polymer

The ETS Group GLK429 extended magazine increases Glock 42 capacity from 6 to 9 rounds while maintaining the pistol's concealability. This clear polymer magazine allows instant visual confirmation of remaining ammunition and features ETS's proven drop-free reliability.

What Makes This Different

Unlike standard Glock 42 magazines, the GLK429 extends capacity by 50% without significantly increasing grip length. The translucent polymer construction provides immediate round count visibility in low-light conditions. ETS magazines undergo extensive drop testing and are rated for over 10,000 loading cycles, matching OEM durability standards while offering enhanced capacity.

Key Features

• 9-round capacity extends standard Glock 42 from 6 to 9 rounds
• Clear polymer body allows instant visual ammunition confirmation
• Drop-free design ensures reliable ejection during tactical reloads
• Reinforced polymer construction resists impact and chemical damage
• Extended baseplate adds minimal length while maximizing capacity
• Compatible with all Glock 42 pistols chambered in 380 ACP

The GLK429 performs consistently across temperature extremes and maintains spring tension through extended storage periods. Competition shooters benefit from the increased capacity during IDPA matches, while concealed carriers gain three additional rounds without printing concerns. The clear body material resists cracking under repeated loading stress and provides chemical resistance against common cleaning solvents.
