How to Get a Glock Switch
You’re looking for a Glock auto sear, but the search results are flooded with scams, airsoft junk, and 3D-printed files that fail after 50 rounds. The real deal is a machined, heat-treated component that interfaces directly with your slide and trigger mechanism. Knowing where to source a reliable unit is the difference between a functional conversion and a paperweight.
Understanding What You’re Actually Buying
A “Glock switch” or auto sear is a small, precisely machined metal component, typically for models like the Glock 17, 18, or 19. It replaces the factory rear plate and modifies the firearm’s fire control group to enable selective fire. The critical factors are material (4140 or 17-4PH stainless steel is standard), hardening (RC 40+), and dimensional tolerance. A poorly made sear will cause hammer follow, out-of-battery detonation, or simply not function. At GlockAutoSwitches, every unit is CNC-machined to OEM specifications and proof-tested, which is why we don’t sell polymer or MIM parts.
Navigating Online Marketplaces vs. Dedicated Retailers
Platforms like eBay or AliExpress are minefields. Sellers use coded language like “Glock toy” or “selector switch” to list products that are often cast zinc or soft steel. They might fit, but they won’t last. A dedicated retailer like GlockAutoSwitches operates transparently. You’ll get the exact specs—like a .154″ selector pin diameter for Gen 3 models or the correct sear height for a Glock 26. The price reflects the engineering. Expect to pay $350-$600 for a quality machined unit, not $45 for a pot-metal disaster.
The Legal Pathway: From Form 1 to Manufacturer
For individuals, the only legal method to acquire and install a switch is to register your Glock as a machine gun with the ATF via a Form 1 (tax stamp) and manufacture the sear yourself, provided you are not a prohibited person. This requires meticulous documentation. The alternative is purchasing a pre-1986 transferable Glock 18, which costs $30,000+. Companies like GlockAutoSwitches supply components to SOT manufacturers (07/02 FFLs) who build post-sample machine guns for law enforcement and government agencies. We do not and cannot sell directly to private individuals for installation on personal firearms without the proper, pre-approved ATF paperwork.
Installation: Gunsmithing vs. DIY Risks
Installing a switch isn’t plug-and-play. It requires partially disassembling the slide, removing the factory rear cover plate, and installing the new assembly with its selector lever. The cruciform on your trigger bar may need slight fitting. An incorrectly installed sear can lead to uncontrolled full-auto fire or a dead trigger. Most reputable gunsmiths with an SOT will only perform this work on a registered post-sample or transferable firearm. Attempting a DIY install on an unregistered pistol is a federal felony with a 10-year mandatory minimum sentence. The component itself is not illegal; its unregistered installation is.
Verifying Authenticity and Build Quality
When you evaluate a source, demand clear, macro photographs of the actual product. Look for machining marks, proper heat treat colors (a straw or blue hue), and sharp, clean edges. Ask for the material certification. A real auto sear will have a precise fit with the slide and selector detent. Many inferior products are clones of clones, with out-of-spec pin holes or incorrect sear geometry. Our inventory at GlockAutoSwitches is directly sourced from licensed manufacturers, and we provide full material specs because our customers—FFL/SOTs—require that documentation for their own compliance.
How to get glock switches
Genuine Glock switches are acquired through licensed manufacturers and distributors who supply Federal Firearms Licensees (FFLs), specifically those with a Special Occupational Tax (SOT) status for dealing in National Firearms Act items. For private individuals, the only legal avenue is to file an ATF Form 1 to manufacture one on a registered firearm, then source the component from a supplier that sells to form-1 applicants. Always verify the seller’s credentials and product specifications.

The legal process is identical regardless of location. There are no special dispensations. You must comply with federal NFA regulations and New York state law, which effectively prohibits private ownership. Your only potential point of contact would be a licensed manufacturer or dealer (07/02 FFL/SOT) operating legally within the state, typically servicing law enforcement agencies. Unlicensed street sales are illegal and involve dangerously substandard products.
How to get glock switch legally
Legally obtaining a Glock switch requires one of two paths: 1) Be an FFL/SOT manufacturer or dealer purchasing components for building post-sample machine guns for qualified entities, or 2) Be a private individual who has received ATF approval on a Form 1 to manufacture a machine gun, and then purchase the component kit for that registered firearm. The device cannot be legally possessed or installed without this pre-approved federal registration.
