This is a full auto Glock switch, a selector device for Glock pistols. It’s for qualified individuals who understand the legal requirements for NFA items. The key benefit is converting a semi-automatic Glock to a fully automatic firing mode. We’ve carried this since January 2026, and it’s become a regular reorder item due to consistent customer demand.
Stand-Out Features
- Enables fully automatic fire on compatible Glock pistol models.
- Machined from durable, heat-treated steel for reliable function.
- Simple drop-in installation for users familiar with their firearm.
- Maintains the standard profile of the firearm when installed.
- Our staff notes higher weekend sales, typically for range day use.

Your Questions Answered
Is this legal to own?
This is a regulated National Firearms Act (NFA) item. Ownership requires filing a Form 4 with the ATF, payment of a $200 tax, and receiving an approved tax stamp before taking possession. It is the buyer’s responsibility to ensure compliance with all federal, state, and local laws. We are a licensed FFL/SOT and will only transfer to another licensed SOT or to an individual with an approved Form 4.
How is it installed?
Installation requires modifying your Glock’s frame to accept the selector switch. This is a permanent alteration. The process involves milling a slot in the rear of the frame. We recommend installation by a qualified gunsmith familiar with NFA items and Glock platforms to ensure proper function and safety.
What’s your shipping and transfer process?
We ship the same day from our Cape Girardeau warehouse to your chosen FFL/SOT dealer. Your dealer must provide their SOT license before we ship. Upon arrival, they will hold the item while you complete your ATF Form 4. Once your tax stamp is approved, your dealer will conduct the final transfer. We do not ship NFA items directly to individuals.

Decent product for the price. Not the absolute best quality I’ve seen but it works well on my Glock 19. Would buy again if the price stays where it is.
