3D printed guns get a lot of attention these days. People think that you can push the print button and out comes a fully functional firearm. The technology just isn’t there. I doubt we will be able to print out a complete firearm any time soon. Regardless, the media frenzy has people panicking about 3D printing.
Sintercore is capitalizing on that media wave and the real potential of the technology. They’re producing a plus 2 magazine extension for the most popular firearm of 2015 (the Glock 43). And the technology allows them to produce the extensions at a much lower price point.

Does the 3DPlus2 work?
These parts are strong. Relying only on the lips of the magazine for retention, they install with a stern click. Once fully seated, installation is complete. The extension itself is actually printed from a stronger polymer than the magazine it’s attached too, but shares a lot of the characteristics of the GLOCK’s polymer frame–mostly the texture and feel in the shooter’s hand.
The angle of the extension is a much more natural line than other extensions on the market. It actually feels like the grip just continues down in a straight line instead of a hook or curve.
This also helps when indexing magazines into the well, as the angle your hand feels is the angle of the mag as it is moving–that is hard to explain, but you know what I mean. There is little to no chance of missing your mark.
Load the magazine and you quickly appreciate the extension. The GLOCK 43 is slim, but has a small gas tank. 8 rounds is always better than 6. Loading is easy due to the use of the factory spring. With more room in the mag, the spring is under slightly less tension which makes loading that much easier.
Is the 3DPlus2 reliable?
I have had the extension on for the past two months and have taken it to the range on all occasions. I’ve got roughly 500 + rounds through it and I have had absolutely no issues. The spring is more than strong enough to engage the slide stop every time it goes empty, and there have been no failures to feed.
Will it be as reliable as the standard GLOCK 43 magazine? Probably not, but I have yet to see a failure or sign of impending doom in all of this shooting. The fact is GLOCK’s are over built; they are designed to be able to shoot in any conditions–no matter how dirty or gummed up. Under normal civilian EDC conditions, even at the muddy shooting range, these mags will almost always work.
In the End
The 3DPlus2 is a great product at a great price. They are cool, available, and worth every penny of $20.00 if you own a GLOCK 43 and carry it daily.
