How to Get Glock Switches: A Real-World Guide for the Informed Buyer

You’re looking at your Gen 5 Glock 19, and you know that factory trigger reset is leaving performance on the table. You’ve heard the term “Glock switch,” but the market is flooded with misinformation, cheap knock-offs, and legal gray areas. Getting a functional, reliable auto sear isn’t about finding a sketchy link; it’s about understanding the components, the law, and sourcing from a vendor that doesn’t cut corners. This is the reality of the switch game.

Understanding What You’re Actually Buying

First, let’s be precise. A “Glock switch” is commonly a small, aftermarket component—often a selector plate or an auto sear—that modifies the firearm’s fire control group to enable automatic fire. It is not a magical button. The most sought-after designs mimic the functionality of the OEM Glock 18 component but are engineered for aftermarket installation. Key variations include the simple “lightning link” style for .22LR conversions and the more complex full-auto sear kits for 9mm models. Knowing the difference between a drop-in auto sear (DIAS) and a selector plate modification is your first step. A poorly machined sear can lead to catastrophic out-of-battery detonations, which is why material quality and tolerances are non-negotiable. At Glockfullautoswitches, we only stock components machined from certified tool steel, not cast zinc alloy.

The Legal Landscape: NFA and Manufacturer’s Licenses

This is the critical section. Under the National Firearms Act (NFA), a machine gun is defined by its capability to fire more than one cartridge per function of the trigger. Any part designed and intended solely for converting a weapon into a machine gun is itself a machine gun under federal law (26 U.S.C. § 5845(b)). Therefore, possessing an unregistered auto sear is a felony. The only legal way for a civilian to acquire one is through a federally licensed manufacturer (07 FFL) with a Special Occupational Tax (SOT) stamp, who can then transfer a registered, tax-stamped machine gun to an individual in a state where they are legal, following a Form 4 transfer with a $200 tax and an extensive background check. Possessing a post-1986 dealer sample requires an 03 SOT. This isn’t a suggestion; it’s the letter of the law.

Identifying Quality vs. Junk

If you’re navigating the legal manufacturing or dealer channels, quality is paramount. A real switch isn’t a $50 CNC-milled toy from a dubious online forum. Examine the finish: it should be a consistent, hard-anodized or nitrided coating, not spray paint. The engagement surfaces—the sear nose and the trigger bar cruciform—must be mirror-polished to reduce friction and wear. Weight is a tell: a proper steel sear has a substantial feel. Packaging matters, too; professional manufacturers include specific installation instructions and often proprietary tools. We’ve tested switches that sheared after 200 rounds and others that have exceeded 10,000. The difference is always in the metallurgy and precision. You can browse categories on our site to see the detailed specs and manufacturing origins of every component we offer.

Installation: Professional Gunsmithing is Not Optional

Do not attempt to install a registered auto sear yourself unless you are a qualified armorer. The process involves precise fitting of the sear to your specific Glock’s frame and slide, often requiring modification to the ejector housing, trigger mechanism housing, and slide. Incorrect sear engagement depth will cause either a failure to fire or a runaway full-auto cycle that won’t stop—a “cook-off.” A professional will also perform a function check with primed dummy rounds and a thorough headspace verification. This is not a Glock Store “Gadget” install; it’s serious gunsmithing. The cost of a proper install from an NFA-certified smith often exceeds the cost of the registered sear itself, but it is the only safe and reliable path.

Where to Source Legally and Securely

Your sourcing options are narrow and well-defined. For new-manufacture registered sears, you must work directly with a licensed 07/02 SOT manufacturer. These entities sell complete, serialized registered sears or converted pistols. The secondary market for pre-1986 transferable registered sears exists on specialized broker sites and at major NFA auctions, with prices typically starting in the $10,000+ range for a converted Glock 17. Avoid any website, social media page, or individual offering to ship a “switch” to your door with no paperwork. That is an ATF sting or a scam. For components, tools, and information related to legal manufacturing and dealer operations, trusted industry vendors like our store provide the necessary hardware to licensed entities. We verify credentials before any sale.

How to get glock switches

For civilians, the only legal path is to purchase a registered, transferable machine gun (if made before May 1986) from a licensed dealer via a Form 4 with a $200 tax stamp, following a lengthy background check. This requires the firearm to be legal in your state. Any other method involving unregistered components is a federal felony.

The legal process is identical regardless of location: through a Federal Firearms License (FFL) holder specializing in NFA items. However, New York state law and New York City ordinances explicitly ban civilian possession of machine guns. Therefore, it is illegal for a private citizen in the South Bronx or anywhere in New York City to possess a Glock switch or a machine gun, regardless of federal NFA registration.

How to get glock switch legally

Legally obtaining a Glock switch means acquiring a registered machine gun. This is done by finding a pre-1986 transferable registered auto sear or converted pistol through an FFL/SOT, submitting ATF Form 4, paying a $200 tax, and passing an extensive background check. The item must then be transferred to you in a state where machine guns are legal for civilians. There is no legal way to buy just the unregistered component.
