What Makes This Full Auto Glock Switch a Solid Choice?
After handling more of these components than I care to admit, I judge them on two things: material integrity and dimensional precision. This isn’t a toy. The unit we offer is CNC-machined from a solid billet of 6061 aluminum, not a cheap casting or a 3D-printed part you might find from a full auto Glock switch STL file. The anodized finish is consistent, and the sear engagement surfaces are hardened correctly. It’s a straightforward piece of engineering that does one job.
Key Features You Need to Know
- Billet Construction: Machined from 6061-T6 aluminum for a rigid, non-flexing platform.
- Precision Hardened Components: Critical wear points are surface-treated to resist deformation under rapid cycling.
- Drop-In Fit: Designed for specific Glock generations; requires no permanent modification to your firearm.
- Consistent Engagement: The geometry is cut to provide reliable sear reset for sustained fire.
- Discreet Shipping: All orders ship in plain, unmarked packaging from our Boise warehouse.

How Does It Stack Up Against Other Options?
| Feature | Buy Full Auto Glock Switch (Ours) | Budget Import (~$65) | “Premium” Brand (~$250+) |
|---|---|---|---|
| Material | 6061-T6 Billet Aluminum | Pot Metal / Zamak Casting | 7075-T6 or Steel |
| Quality | CNC machined, hardened surfaces | Often rough, out-of-spec, soft | High-precision machining |
| Compatibility | Gen 3 & 4 (Tested) | Varies wildly, poor fit | Specific to model, excellent fit |
| Shipping | Same-day, USA | Weeks from overseas | Varies, often fast |

Pros and Cons: An Honest Assessment
Pros:
- ✅ Domestic CNC Machining: Not a cast or printed part. Tolerances are held tight.
- ✅ Hardened Wear Surfaces: The parts that take the beating are treated to last.
- ✅ Immediate Availability: In stock and ships same-day from Idaho, no backorders.
- ✅ Fair Price Point: At $150, it’s positioned well between junk and overpriced.
- ✅ Discreet & Fast Shipping: You won’t be waiting weeks or getting a suspicious package.
Cons:
- ❌ Not for All Glocks: Compatible with Gen 3 & 4 only. If you need another platform, see our Full Shop for alternatives.
- ❌ Aluminum vs. Steel: For extreme, sustained volume of fire, a steel component has ultimate durability. This is a robust aluminum design.
- ❌ Legal Complexity: This is a regulated NFA item. The onus is entirely on the buyer to ensure lawful possession.
Who Should Buy This Full Auto Switch?
Buy it if: You are an SOT holder, a law enforcement armorer, or a civilian with a properly registered Glock machine gun (Form 4). You want a dependable, domestically-made component that ships now without paying a premium brand markup. You understand the legal framework and your responsibilities.
Skip it if: Your Glock is not an NFA-registered machine gun. You own a Gen 5 or other incompatible model. You are seeking a “novelty” item without the proper paperwork—that is a serious federal crime. You require the absolute highest-end steel construction for institutional use.
Frequently Asked Questions
Is a Glock full auto switch legal?
It is legal to possess only if it is installed on a Glock pistol that is registered as a machine gun under the National Firearms Act (NFA) with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Possession of the switch alone, without the registered host firearm, constitutes possession of an unregistered machine gun, which is a federal felony.
Is it illegal to own a Glock switch?
Yes, it is a federal felony to own a Glock switch (formally, a “machinegun conversion device”) unless it is permanently attached to a firearm that is registered as a machine gun under the NFA. This is not a state-by-state issue; it is controlled by federal law (26 U.S.C. § 5845(b)).
Can you own a Glock switch?
You can only lawfully own one if you are a federally licensed manufacturer (Type 07 FFL with SOT), a dealer in NFA items (Type 01 or 02 FFL with SOT), or a private citizen who has registered the host firearm as a machine gun and received an approved ATF Form 4. There are no exceptions.
Where can I buy a full auto Glock switch online?
You can purchase one from Glockswitchstore (glockswitchstore.com). We are a Boise, ID-based retailer that ships discreetly and quickly to customers with the proper credentials. We do not sell to individuals who cannot demonstrate compliance with federal law.
What’s the difference between this and a 3D printed switch from an STL file?
Night and day. A part from a full auto Glock switch STL file, when printed, is a polymer prototype at best. It lacks the structural integrity and heat resistance for sustained fire. Our switch is machined from aluminum billet with hardened components. One is a functional tool; the other is a range hazard.
I see discussions on Reddit about these. Should I trust that information?
Be extremely cautious. While you may find technical discussions on full auto Glock switch Reddit threads, you must verify any legal advice with a qualified firearms attorney. The legal risks are severe, and internet forums are not a reliable source for legal counsel.
What is your shipping and return policy?
We ship same-day on weekdays from Boise, ID via USPS Priority Mail with discreet packaging. We offer a 30-day return for uninstalled, undamaged items. Due to the nature of the product, all sales are final if the package has been opened or the item installed.
