How to Get Glock Switches

You're looking at a Glock's backplate and wondering how that small piece of polymer can transform the platform. The process isn't about magic; it's about precision parts, legal understanding, and sourcing from a reputable vendor like Fullautoswitch. The switch itself is a simple mechanical component, but obtaining one requires navigating a specific path.

Understanding What a Glock Switch Actually Is

A Glock switch, formally known as an auto sear or selector switch, is a small metal or polymer component that replaces the factory backplate on a Glock pistol. Its function is purely mechanical: it engages with the firearm's trigger mechanism to allow for continuous fire with a single pull of the trigger. Common models include the "Giggle Switch" and the "Glock 18C" style selector. It's crucial to understand that this part, by itself, is inert metal. Its legal status is determined by the National Firearms Act (NFA), which classifies any machinegun, including a Glock modified with one of these devices, as a Title II firearm. Possession without proper registration is a federal felony.

The Legal Pathway: Form 1 and Manufacturer Licensing

The only legal way for a private citizen to acquire and install a Glock switch is to first register the host firearm as a machinegun with the ATF. This is done by submitting an ATF Form 1, "Application to Make and Register a Firearm," along with a $200 tax stamp, passport photos, and fingerprints. Approval can take several months. Once approved, you may manufacture the device yourself (requiring significant machining skill) or purchase the switch component from a licensed manufacturer. The switch must then be permanently installed on the registered firearm. Any other method of acquisition is illegal. Fullautoswitch provides informational resources for those navigating the legal manufacturing process.

Identifying Reputable Sources for Components

If you have an approved Form 1, sourcing a quality switch is critical. Avoid sketchy online forums or social media sellers offering "3D printed files" or "plug-and-play" kits—these are often scams or legally treacherous. Legitimate sources are licensed manufacturers who sell components for registered NFA items. Look for vendors that use certified materials like 4140 or 17-4 PH stainless steel for durability. A proper selector switch should have precise milling, a positive click between positions, and come with the necessary mounting hardware. Always verify the seller's legitimacy and ensure they understand and require proof of your NFA status before any transaction.

Common Pitfalls and How to Avoid Them

The biggest pitfall is attempting to buy a switch without the prerequisite NFA paperwork. Law enforcement actively monitors illegal sales, and "sting" operations are common. Another mistake is purchasing poorly machined components that can fail catastrophically, damaging your firearm and causing injury. Avoid any seller who doesn't ask questions about your licensing. Price is also a major indicator; a real, machined-steel switch from a licensed manufacturer typically costs between $250 and $500. Anything significantly cheaper, especially "plastic" or "DIY" kits advertised for "educational purposes," is a major red flag. For vetted information on components, the Fullautoswitch blog is a reliable resource.

Installation and Function Verification

Once you have the legally registered host firearm and a quality switch, installation is straightforward but requires attention to detail. You'll need a punch set to drive out the rear slide pin. After removing the factory backplate, the switch assembly slides into the same channel. The selector lever must move crisply between its positions. Before live fire, conduct a full function check with dummy rounds to ensure proper sear engagement and disengagement. Remember, this modification drastically increases wear and ammunition consumption. You are responsible for ensuring the device functions safely and remains exclusively on the registered firearm.
