The more they tighten their grip, the more we slip through their fingers:
More 3D printed magazines coming. The people at Defense Distributed are hard at work creating files to print out popular magazines in standard capacities of 10, 15, 17, 25, 30, 33, and 40 rounds. At least one of the people working on the DefCad site has already printed a floor-plate and magazine body for a Glock pistol. The early Glock magazines were made of plastic, so they are well suited for this process.
We will not know how these designs will hold up until they are actually printed and tested. However, 30 round magazines that were prototyped for the KelTec PMR-30 were said to last for 100 to 150 rounds before cracking.
Defense Distributed has already prototyped and demonstrated 30 round magazines for the AR15 platform. The 30 round magazine requires an easily obtained steel spring, but the site has files for a 5 round magazine with a printed plastic spring.
Here is a list of the models that are being worked on at present:
Glock 17, 19, 26, 34, 17 round and 33 round.
AK type 30 round and 40 round.
Saiga 12 gauge 10 round.
S&W M&P .40 cal. 15 round.
This is what happens with a free market. When ideas are liberated, a surplus appears. While the gun grabbers try to limit our right to own high capacity magazines, a market opens up catering to that need.
This is why government bans fail.
