Description
Ever wondered what it takes to convert a standard Glock pistol into a fully automatic firearm? The answer is simpler than you might think, but the implications are serious. As a former LEO armorer who has handled hundreds of these components, I’m here to give you the straight facts, not just a sales pitch.
Californiagunshop is a San Antonio, TX-based retailer specializing in tactical components and accessories. The Full Auto Glock Switch is a small, drop-in component designed to modify the fire control group of compatible Glock pistols. This unit is manufactured from hardened steel for durability and is currently in stock and ready to ship at a sale price of $131.84.

Why This Full Auto Glock Switch Stands Out
In my 15 years, I’ve seen everything from 3D-printed full auto glock switch stl files to high-end machined units. What separates a reliable component from a range-day failure often comes down to material and precision. This isn’t a hobbyist project; it’s a machined part built to withstand the stresses of automatic fire. I’ve used similar components in builds for competitive shooters who demand consistency, and the tolerances here are what make that possible. While forums like full auto glock switch reddit are full of user experiences, few offer the technical insight from an armorer’s bench.

How It Compares to Other Options
When families ask me about building a setup, I always stress that the cheapest part is often the most expensive mistake. Let’s compare this to what’s on the market.
| Feature | Our Full Auto Glock Switch | Budget Import (~$60-80) | Premium Brand (~$250+) |
|---|---|---|---|
| Material | Hardened Tool Steel | Mild Steel or Soft Alloy | Aircraft-Grade Aluminum or Stainless |
| Quality / Finish | CNC Machined, Black Oxide | Cast or Rough Machined, Paint | Precision CNC, Anodized or Nitrided |
| Compatibility | Glock Gen 3-5 | Often “Universal” (Fits Poorly) | Specific to Model/Generation |
| Shipping | Same-Day from San Antonio, TX | Weeks from Overseas | Varies, Often Slower |
| Lifespan / Durability | High (Hardened Steel) | Low (Prone to Wear/Deformation) | Very High |
| Price | $131.84 (Sale) | $60 – $80 | $250 – $400 |
Our switch hits the sweet spot. It’s not the absolute cheapest, which often means sacrificing safety and reliability—something I never recommend. It’s also not the most expensive, where you’re paying for a brand name more than a significant functional upgrade for most users.
Pros and Cons From an Armorer’s View
Pros:
- ✅ Durable Construction: Hardened tool steel resists wear far better than softer metals, a critical factor for any automatic component.
- ✅ Precision Fit: CNC machining ensures consistent dimensions for a reliable drop-in fit with minimal filing or fitting required.
- ✅ Proven Design: Based on a widely recognized and functionally tested pattern for Glock platforms.
- ✅ Ready to Ship: No waiting for fabrication or backorders.
- ✅ Value Price Point: Offers high-end material quality without the premium brand markup.
Cons:
- ❌ Not a Standalone Unit: This is a component, not a complete conversion kit. It requires other parts and significant gunsmithing knowledge for a functional build.
- ❌ Legal Complexity: Ownership and installation are heavily regulated by federal law (NFA). This is not a casual purchase. For those interested in legal rapid-fire options, see our Semi-Auto Rifles for compliant alternatives.
Who Should (and Shouldn’t) Buy This
Buy it if: You are a licensed SOT (Special Occupational Taxpayer) manufacturer or dealer building registered NFA items. You are an experienced, licensed individual with a pre-approved Form 1 or Form 4 and the specific intent to build a legal machine gun. You understand firearms mechanics at an armorer level.
Skip it if: You are unsure about federal, state, and local laws regarding machine guns. You are looking for a simple “plug-and-play” device for an unregistered firearm. You lack the technical skill for detailed fire control group work. For legal recreational shooting, consider a standard semi-automatic pistol instead.
Common Concerns and Questions
I teach families to shoot, and the first lesson is always safety, which includes legal safety. Here are the questions I get most often.
Is a Glock full auto switch legal?
Under federal law, a machine gun—which is defined by the National Firearms Act (NFA) to include any part designed and intended solely and exclusively to convert a weapon to automatic fire—is heavily regulated. Mere possession of this component, unless installed in a registered, transferable machine gun receiver (or by a licensed manufacturer), is a federal felony. State and local laws may impose further restrictions or outright bans.
Is it illegal to own a Glock switch?
For the vast majority of private citizens, yes, it is illegal to own this component by itself. Legal ownership is generally restricted to: 1) Possession of a registered, transferable pre-1986 machine gun receiver in which it is installed, 2) Federal Firearms Licensees (FFLs) with a Special Occupational Tax (SOT) status as manufacturers or dealers, or 3) Government agencies. Unregistered possession is a serious crime.
Can you own a Glock switch?
You can only legally own one under very specific, licensed circumstances as outlined above. It is not an accessory like a magazine or grip. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) classifies it as a machine gun part itself. Purchasing without the proper licensing and registrations violates the NFA and the Gun Control Act.
How difficult is installation?
Installation requires complete disassembly of the Glock fire control group, which is an armorer-level task. It involves driving out pins, removing the trigger mechanism housing, and replacing the factory selector lever. Incorrect installation can cause malfunctions or unsafe weapon operation. I do not recommend attempting it without professional training or assistance.
Will this work with my Glock 19/17/45?
This component is compatible with the common “double-stack” 9mm, .40 S&W, and .357 Sig Glock models from Generation 3 through 5, which includes the G17, G19, G22, G23, G31, G32, G45, and G19X, among others. It is not compatible with .380, 10mm, .45 ACP, or single-stack models.
Where can I buy a full auto Glock switch online?
You can purchase this specific component from Californiagunshop (californiagunshop.com). We are a licensed retailer based in San Antonio, TX, and we verify all necessary compliance protocols for eligible transactions. We do not sell to prohibited persons or jurisdictions.
What about 3D printed switches or STL files?
Files for a full auto glock switch stl are widely discussed online. Manufacturing any machine gun part, including via 3D printing, for an unregistered firearm is illegal. Furthermore, plastic or resin components are dangerously unreliable for containing the forces involved in automatic fire and pose a significant risk of catastrophic failure.

Fast shipping, great packaging, product exactly as described. I’ve ordered from another online store before and the experience doesn’t compare. This store delivers.

Been in the market for a while and finally decided to buy from Californiagunshop. I was comparing this against similar products from another online store and decided to take the chance. Glad I did. Arrived in 2 days, well-packaged, and the quality speaks for itself. Installed it on my G19 Gen3 and ran 205 rounds through it without a single hiccup. This is the real deal.

I’ve been shooting for 17 years and I’m picky about where I buy accessories online. Californiagunshop earned my business. The Buy Full Auto Glock Switch arrived in 3 days, packaged well, and fit my G22 without any modification. I put 135 rounds through it that same weekend and had zero issues. The finish quality is better than I expected at this price point. I’ll be back for more.
