Search interest in the “Super Safety” is climbing, and a lot of people lump it together with forced reset triggers. They are not the same thing, and the difference is the difference between a legal part and a federal felony. Here is the plain version.
A Super Safety is a drop-in device marketed to make a semi-automatic rifle fire continuously. In function it works like an auto sear — it defeats the normal single-shot cycle so the firearm keeps firing from one action of the trigger.
Under the National Firearms Act and 18 U.S.C. § 922(o), a machine gun includes any part or device designed to convert a weapon into one that fires more than one shot per function of the trigger. The ATF treats Super Safety devices as exactly that — machine-gun conversion devices. Possessing one is possessing an unregistered machine gun, a federal felony carrying up to 10 years in prison, and because civilian machine-gun registration closed in 1986 it cannot be made legal after the fact.
We do not sell the Super Safety or any machine-gun conversion device, and nothing on this site should be read as encouraging you to obtain one. This page exists to explain the difference, not to point you toward an illegal part.
A forced reset trigger fires one round per pull of the trigger. Its reset is mechanical and fast, but you must deliberately press the trigger again for every shot. That single fact — one function, one round — is why an FRT is treated as a semi-automatic component and a Super Safety is treated as a machine gun.
If what you actually want is a faster, snappier semi-automatic trigger, that is what an FRT provides — legally, where permitted. For a Glock that means our Glock FRT kit; for the wider picture see what a forced reset trigger is.
The same rule applies to any device sold to make a firearm fire automatically — including MP5-pattern conversion parts and Glock “switches” or auto sears. They are machine guns under federal law. See our explainer on switches.
No. The ATF treats Super Safety devices as machine-gun conversion devices. Possessing one is a federal felony, and it cannot be registered.
No. A Super Safety is designed to make a gun fire automatically. A forced reset trigger fires one round per trigger pull and is a semi-automatic component.
No. We sell only the semi-automatic Glock FRT. We do not sell machine-gun conversion devices of any kind.
