Plastic guns, or guns that incorporate a significant amount of plastic or polymer materials in their construction, have become increasingly common. While revolvers have not yet gone plastic, semi-automatic handguns and pistols have. The use of plastic in guns began with the Austrian manufacturer Glock, which replaced much of the steel in guns with nylon. While plastic guns are cheaper and lighter, they are not as durable as metal guns. Additionally, despite initial fears, plastic guns are detectable by metal detectors and X-ray machines.

What You'll Learn

Plastic guns are possible, but they are hybrids, not entirely plastic
The use of plastic in gun manufacturing began in the 1980s with the Austrian company Glock, which aimed to reduce the cost of guns by using plastic for as much of the gun as possible. Nylon was used for the "frame" or body of the gun, while the top part or "slide," which houses the barrel, remained metal. The Glock 17 prototype was extensively tested and eventually adopted by the Austrian military, leading to the widespread use of nylon-framed guns by other manufacturers.
Today, semi-automatic handguns or pistols have incorporated plastic or polymer materials in their construction, particularly in the lower receiver and grip, due to their lightweight and corrosion-resistant properties. However, it's important to note that the specifics of plastic guns may change due to evolving technologies and regulations, and there may be regional variations in the development and legal status of such weapons.
While 3D printing technology has made it possible to create almost completely plastic pistols, such as the "Liberator," these are typically designed for single-use or emergency situations. The durability and strength of plastic guns, especially those made with 3D printing technology, are still questioned, and metal components are often necessary to ensure the firearm's functionality and safety.

Plastic guns are often referred to as polymer guns
Guns made entirely of plastic do exist, but they are not common. Plastic guns often refer to firearms constructed with a significant amount of plastic or polymer materials, mixed with metal components. Polymer materials are engineered to be strong and durable, and they are reinforced with additives to withstand the stress and pressure when a firearm is discharged.
Plastic guns are typically referred to as polymer guns because not all plastics are like what most people consider plastic. Polymer materials are lightweight, corrosion-resistant, and cost-effective. They are also not susceptible to rust like traditional metal components. However, they may be less durable than metal guns and might not withstand heavy use or high round counts.
Polymer guns have gained popularity due to their lightweight and durable nature. They are commonly used in modern firearms, with critical components like the barrel and firing assembly still made from steel or other metals. The lower receiver and grip of a firearm often contain plastic components, housing the trigger mechanism, magazine well, and stock.
The use of polymer materials in guns is not new, and they have been proven in duty, war, and with everyday concealed carriers. Examples of guns with polymer parts include the stock and forearm of the M16 and the lower frame of the Glock. Polymer frames, grips, and stocks have existed for a while and are prevalent in modern firearms.
While complete plastic guns are possible, such as the "Liberator," which can be 3D printed, they are not as common as firearms with a mix of metal and polymer components. The legality of plastic guns also varies by jurisdiction, with some places heavily regulating or prohibiting the creation or possession of 3D-printed firearms due to concerns about untraceability and detectability.

The Glock 17 was the first all-plastic gun
The Glock 17, introduced in 1979, was the first all-plastic gun. It was the first commercially successful pistol with a polymer frame. Its Austrian creator, Gaston Glock, had no prior experience with firearms design or manufacture, but he did have extensive experience in advanced synthetic polymers. This proved instrumental in the design of the Glock 17.
The Glock 17 is a 9mm semi-automatic pistol that ships with 17-round steel-reinforced polymer body magazines. It is renowned for its simplicity, reliability, and durability. Its polymer frame makes it significantly lighter than most other guns, weighing just 25 ounces. Its proprietary Tenifer finish is highly corrosion-resistant, and its surface is non-glare.
The Glock 17 was initially adopted by the Austrian military and law enforcement in 1982, outperforming pistols from five other established manufacturers. It has since been adopted by more than half of the police departments in the United States. The Glock 17 was also the most reliable, commercially-made semi-automatic pistol for over two decades.
While the Glock 17 is considered the first all-plastic gun, it is important to note that not all of its parts are plastic. Some metal components are necessary, such as the barrel and firing pin. However, the extensive use of polymer in the Glock 17's design revolutionized the firearms industry, and it remains a highly influential and popular weapon even today.

Plastic guns are significantly cheaper than steel-framed guns
Guns have traditionally been made of steel, with grips made of hard rubber or plastic. However, modern guns have increasingly incorporated polymer plastics into their design. While some parts of a gun, such as the barrel, receiver, and firing assembly, are still made from metal, other parts, such as the stock, forearm, and lower frame, are often made of polymer.
Polymer frames for handguns were pioneered by Heckler & Koch with the VP70 in 1970. The Glock pistol, introduced in the 1980s, also used a polymer frame and faced opposition due to its plastic design. Despite this, Glock pistols have become widely adopted by law enforcement agencies and civilians.
Plastic guns, or polymer-framed guns, offer several advantages over their steel counterparts. One of the most significant benefits is the reduced cost of manufacturing due to the lower price of polymer compared to steel. Polymer guns are also lighter in weight, making them easier to carry and reducing recoil. Additionally, polymer does not rust, enhancing the reliability of the weapon.
While steel-framed guns offer advantages in durability and recoil reduction, plastic guns have become popular due to their cost-effectiveness, lightweight design, and resistance to corrosion. The use of plastic in gun design has allowed for innovations in the firearm industry, providing an alternative to traditional steel-framed guns.

Plastic guns are not invisible to metal detectors and X-ray machines
Plastic guns incorporate a significant amount of plastic or polymer materials in their construction, especially in their lower receivers and grips. However, they still contain critical metal components such as the barrel, firing pin, and other parts necessary for the firearm's functionality. Therefore, plastic guns are not invisible to metal detectors and X-ray machines.
The idea that plastic guns would be invisible to metal detectors and X-ray machines was initially a concern when guns started to incorporate plastic components. However, this concern has proven to be unfounded. While plastic guns may contain a significant amount of plastic, they still have metal parts that can be detected by metal detectors and X-ray machines.
The barrel of a gun, for example, is typically made of metal to provide the necessary strength and durability. Other high-stress-bearing parts like bolts are also usually made of metal. These metal components ensure that plastic guns are detectable by metal detectors and visible on X-ray scans.
Additionally, plastic guns often have metal components in the trigger mechanism and the clip. These metal parts are essential for the gun's functionality and further contribute to its detectability by metal detectors and X-ray machines. Overall, while plastic guns may have a significant plastic composition, they are not completely metal-free and can be identified by standard security measures.
It is worth noting that the specific composition of plastic guns may vary due to evolving technologies and regulations. Different manufacturers may use different materials and designs, resulting in variations in the amount and placement of plastic and metal components. Therefore, it is important to stay informed about the latest developments and legal requirements regarding plastic guns in your region.
