Sintercore’s New 3DPlus2 Mag Extension

sintercore1

Sintercore, the veteran-owned business responsible for the first commercially-available 3D-printed muzzle brake, among other items, is coming out with something new: a 3D-printed magazine extension for the Glock 43. The mag extension is called the 3DPlus2 and was designed in a collaborative effort with Eric Mutchler, the man behind the Solid Concepts 1911, the first 3D-printed metal handgun in the world. Between Mutchler’s innovation and Sintercore’s reputation for quality, the 3DPlus2 promises to be not only a good product but also an important piece of the 3D-printing industry.TFB Previous Article

As the name implies, the 3DPlus2 adds two more rounds to the Glock 43’s factory magazine, so you’re given both a pinkie extension and a bit more ammo. It’s being produced in carbon-filled nylon, which is not only durable but stronger than the pistol’s factory magazines, according to the company. The design is ergonomically correct, so the shooter’s grip continues naturally, and it’s easy to install. There are no screws or fasteners needed; the 3DPlus2 simply snaps into place, working with the gun’s factory spring. Removal is also easy thanks to a hole in the bottom of the extension, which allows for compression of the spring.

The extension is currently set to be shipped in early August of 2015, but you can pre-order yours today. MSRP is $19.95. Take a look on the company’s website at http://sintercore.com/3dplus2/ and watch the videos below for a closer look at the mag extension’s durability and design.

      Lol.

    I guess that’s pretty nifty. In my opinion, the G43 should probably have had an 8-round magazine in the first place (or at least have it as an option).

    + mag extensions are eh. I wouldn’t trust the reliability and don’t like the way they look.

    For what it’s worth, that isn’t a bad price if these are really 3d printed. That material is at least twice as expensive as PLA and then you have machine time to consider. Printing takes longer than doing bulk molds.

    I wish companies would share their files for those who do have printers, but I understand not everyone is into OpenHardware.

    I pre ordered two last night…..now I will wait and see.
