When it comes to the history of firearm manufacturing, guns are one of the oldest products on record that have been modified or customized from inception for its end user, whether he or she was a war general, a high class citizen or even a cowboy.  

Today, with the ability to easily modify nearly any existing product to better suit one’s taste, it’s no surprise that 3D printing has been becoming increasingly popular with gun enthusiasts who are looking to further modify their firearms for a variety of applications.

Among other companies who have been actively exploring the intersection of firearms and additive manufacturing include Michigan-based Sintercore, a veteran-owned business who are responsible for creating the world’s first commercial 3D printed Inconel alloy flash-hiding muzzle brake, the 3DX.  The company has recently unveiled their latest project, the 3Dplus2, an extended magazine for the popular Glock 43 pistol.     

Similar to the 3DX brake, Sintercore started with 3D printing from the get-go to develop their 3Dplus2, which is printed with carbon-reinforced nylon which is designed to exceed the factory magazine components and is “tougher than the magazine itself.”

In total, the 3D printed magazine extension adds an additional two rounds to the concealed-carry pistol which bring the total up to 8+2 rounds of 9mm Luger.  Additionally, the mod extends lower than the existing baseplate and subsquently provides extra grip space for fingers and those needing more control.

Developed with Eric Mutchler, inventor of the first 3D printed handgun in the world, the SC1911, the magazine extension is a perfect example of how additive manufacturing can be used to make mass manufactured products more personal or better suited to one’s individual needs with little extra effort.  While previous efforts haven’t been able to hold up well due to weak materials, the introduction of carbon-reinforced filaments has made it possible for design engineers to create parts that are more functional for high-impact scenarios.  

Currently, the company is taking pre-orders for the $19.95 3D printed magazine extensions and anybody who pre-orders is automatically entered to win their choice of a Sintercore Tripwire charging handle or a $50 Brownells gift certificate.
