Thinking about installing a Glock switch but not sure if it’s legal where you live? You’re not alone. Glock switches — often called full auto sears — are one of the most misunderstood firearm accessories in the U.S. Due to their ability to convert a semi-auto Glock into a fully automatic weapon, these devices are highly regulated at the federal and state levels.
Let’s break down what’s legal, what’s not, and how you can check Glock switch legality in your state.
What Is a Glock Switch, Legally?
A Glock switch is considered a “machine gun conversion device” under the National Firearms Act (NFA). That means even owning one — not just using it — is treated as owning a machine gun.
At the federal level, Glock switches are legal to own ONLY if:
- You have an FFL (Federal Firearms License)
- The switch is registered under the NFA
- You’ve paid the $200 tax stamp
- You’ve received ATF approval
Failing to meet those requirements can result in felony charges, 10+ years in prison, and permanent loss of firearm rights.

What to Do If Your State Allows Glock Switches
If your state permits full-auto ownership under NFA regulations:
- Apply for a Tax Stamp (ATF Form 1 or Form 4)
- Purchase from an FFL or SOT dealer
- Ensure the device is serialized and properly registered
- Wait for approval before installation
