Frequently Asked Questions

Will this magazine work in my Glock 42?

Yes. The ETS GLK42 7-round magazine is designed specifically for the Glock 42 and its .380 ACP chambering.

What's the advantage of a clear polymer magazine?

The transparent construction lets you see your remaining rounds without removing the magazine from your gun or gear. This is especially handy during training or in a defensive scenario where quick status checks matter. The polymer material also resists rust and corrosion better than bare metal, so your spare mags stay mission-ready even if they're stored in a vehicle or range bag exposed to moisture.

How many rounds does it hold?

This magazine holds 7 rounds of .380 ACP ammunition, matching the standard single-stack capacity of the Glock 42.

Should I carry multiple spare magazines?

That's a personal choice based on your training and role—whether you're a competitive shooter, dedicated range enthusiast, or carry gun owner. Having at least one spare magazine is a best practice for any firearm owner, so you can reload during practice, maintain rotation to extend spring life, or have a backup if one mag develops an issue.
