USE YOUR GUN PROPERLY & LAWFULLY
An essential part of responsible gun ownership is knowing federal and local gun laws and always carrying responsibly. This means staying up-to-date on the laws in your area and taking time to train with your firearm. Violating gun laws can have severe and lasting consequences. The proper and safe function of your firearm depends on it being used for its intended purposes and not being altered or modified. Avoid altering or modifying your firearm from its original condition. Any attempt at converting your firearm from semiautomatic to fully automatic through the use of any device is illegal and strictly prohibited under state and federal laws and strongly discouraged by GLOCK. Follow the law and stay informed of laws applicable to the purchase, sale, and use of your firearm. Never use your firearm unlawfully.
MAKE SAFETY YOUR TARGET – AVOID ILLEGAL MODIFICATIONS!
Machinegun Conversion Devices (“MCDs”), also known as “switches” or “auto sears,” are a serious issue. These devices are illegal and pose significant dangers to public safety. GLOCK has no affiliation with MCDs and does not support their manufacture, use, advertisement, or sale. According to the Bureau of Alcohol, Tobacco, Firearms, and Explosives (“ATF”), one of the most prominent emerging public and law enforcement officer safety threats in recent years has been the proliferation of illegal MCDs. MCDs are defined as machineguns under the National Firearms Act, even when not installed. Machineguns, including MCDs, may not be possessed or transferred under Federal law, with limited exceptions. MCDs include traditional “Drop In Auto Sears,” which are designed for use on AR-type firearms, and more recently developed “switches,” which are designed for use on certain semiautomatic pistols. MCDs include those pictured below:
Modifying a firearm by adding an illegal device that overrides the original, intended function or design to render a semiautomatic firearm into an automatic firearm is a felony. That includes importing, possessing, making or selling a machinegun conversion device (MCD). It’s a violation of the National Firearms Act (NFA) and carries a prison sentence of up to 10 years and up to $250,000 in fines.
