Glock Magazine for Glock Model 42 .380 ACP 6 Round – MF42006

This Glock Magazine for Glock Model 42 pistols in .380 ACP holds 6 rounds and carries part number MF42006, and it is the factory article rather than an aftermarket approximation. Magazines are the most common source of malfunctions in any semi automatic pistol, which is precisely why buying factory matters. For a carry gun, spares are not optional equipment.

Why a Factory Glock Magazine for Glock Pistols Matters

Feed lips, follower geometry, and spring rate are what determine whether a pistol runs. Aftermarket magazines vary widely in how carefully those three things are controlled, and a magazine that is even slightly out of specification will produce failures to feed that owners then blame on the gun, the ammunition, or themselves.

The G42 is a small pistol chambered in .380 ACP, and small pistols are less tolerant of magazine variation than full size guns because there is less slide mass and less margin in the feed cycle. A factory magazine from Glock removes that variable entirely. If your G42 is your carry gun, this is not the place to save a few dollars.

Key Features of This Magazine

• Factory Glock production, built to the same specification as the magazine your pistol shipped with.
• 6 round capacity in .380 ACP, matching the standard configuration for the Model 42.
• Designed specifically for the Glock 42, so feed lip geometry and follower profile match the pistol exactly.
• Part number MF42006 for straightforward reordering when you want a matched set of spares.
• Durable polymer body over a steel liner, the construction that made Glock magazines a benchmark for reliability.

Specifications and What They Mean

Six rounds is the standard capacity for the G42, and that number is a consequence of the pistol’s size rather than a limitation to be engineered around. A single stack .380 in a genuinely pocketable frame is going to hold six, and the shooter’s answer to that is carrying spares rather than forcing an extended magazine that compromises the grip.

The .380 ACP chambering means comparatively low pressure and a short cartridge, both of which put more importance on precise feed timing. The follower has to present the round at the correct angle with the correct spring pressure every time, or the slide will outrun the magazine. Factory tolerances are what make that consistent. Capacity also drives how the pistol carries, since a flush fitting six round magazine keeps the grip short enough to disappear in a pocket holster, while an extended baseplate changes that profile entirely.

Practical Use, Rotation, and Care

Number your magazines with a paint pen or a small label. If you ever experience a malfunction, you want to know which magazine was in the gun, because a single bad magazine is the most common cause of intermittent problems and it is impossible to identify without tracking.

Rotate carry magazines rather than leaving one loaded indefinitely. Modern springs handle sustained compression far better than folklore suggests, but rotation is free and it gives you a reason to inspect each magazine periodically. Cycle every magazine at the range so you know all of them work, not just the ones that happen to be in the bag. Treat a Glock Magazine for Glock pistols as a wear item rather than a permanent fixture, and retire any that show cracked feed lips or a tired spring.

Disassemble and clean magazines occasionally, especially if they live in a pocket where lint accumulates. Wipe the body, clean the follower and spring, and check the feed lips for damage or spreading. Do not lubricate the inside of a magazine, since oil attracts debris and can contaminate ammunition. For holsters, mag carriers, and other accessories, browse the parts and upgrades category.
