Glock 42 Magazine With Extension .380 ACP 6 Round – MF08833

This Glock Magazine With Extension for the Glock 42 holds 6 rounds of .380 ACP and adds the grip length that makes a pocket sized pistol genuinely shootable. The Glock 42 is one of the smallest pistols the company builds, and the tradeoff for that size is a grip that leaves most adult hands with a finger hanging in space. A magazine extension solves that problem without changing the pistol itself. It is the classic first upgrade for anyone carrying this pistol seriously.

Small pistols are easy to carry and harder to shoot well. Glock built the 42 around exactly that compromise, so anything that restores control without adding meaningful bulk is worth having.

What This Glock Magazine With Extension Changes

The extension adds length below the frame so your little finger has a purchase on the gun rather than curling underneath it. That single change improves recoil control, speeds up follow up shots, and makes extended practice sessions far more comfortable. Shooters routinely find their groups tighten immediately.

The 6 round capacity keeps the pistol topped off for defensive use, and having spare magazines on hand means less time loading and more time shooting during practice. Carrying at least one spare is standard practice for any single stack carry gun.

It suits concealed carriers, new shooters working through their first .380, and anyone who finds a flush fit magazine uncomfortable to shoot.

Key Features

• 6 round capacity in .380 ACP for the Glock 42
• Integrated extension that adds grip length for a full finger purchase
• Improves recoil control and follow up shot speed on a small framed pistol
• Genuine Glock component built to the same standard as the pistol itself
• Steel lined polymer body that survives drops during reload practice

Specifications and Fitment

Fitment is model specific, and that matters. This magazine is built for the Glock 42 in .380 ACP, and it will not interchange with the Glock 43 or any 9mm model despite the external similarity between those pistols. Confirm your model marking on the slide before ordering.

The 6 round capacity is one more than the standard flush fit magazine for the platform, so the Glock Magazine With Extension gives you both a longer grip and an additional round. Steel lined polymer construction follows the same pattern used across the company’s magazine line, which is why these hold up so well over years of use.

Carry, Practice, and Maintenance

Consider how the extension interacts with concealment. On most carriers the added length is negligible under a shirt, but if you pocket carry the Glock 42 you should check the printing and holster fit before committing. Many owners carry flush fit in the gun and extended magazines as spares.

Practice reloads with the same magazines you carry. Seating a magazine firmly is more difficult on a small pistol because there is less grip to brace against, and building that habit takes repetitions rather than theory.

The .380 ACP chambering deserves a note as well. It is a mild recoiling cartridge that suits shooters with limited hand strength, and the added grip length from the extension makes the pistol easier to hold steady through a full magazine.

Maintenance is simple. Unload, remove the floorplate while controlling the spring, wipe out powder residue and lint, and reassemble dry. Rotate loaded magazines periodically and replace any with damaged feed lips. Magazine regulations vary by jurisdiction, so confirm your state and local law before ordering, and see our parts and upgrades collection for holsters, sights, and other components.

For a few dollars a Glock Magazine With Extension gets you a better grip, an extra round, and a pistol that is genuinely more pleasant to shoot. Buy two and keep one in the gun. Ships direct to your door, no FFL required.
