So not only do you have to put a mag in, or unfold it to get the pistol to work, but the onboard mag pouch makes it far bulkier than a plain pistol. Some ideas look cool, or you can see where it might pay off down the road, this thing looks like nothing but fail.
The actual "folding Glock" concept appears to be a workable thing.
(the second one in that video @ 1:48 / The F-3)
1) Deployment does not require pulling a mag from the from and inserting it into the pistol.
2) It is carried with one round already in the chamber.
3) There is a full size normal grip when it is deployed.
4) There is a full trigger guard.
5) The pistol can be carried differently due to the grip being folded up under the slide.
The first pistol with the magazine becoming the grip... Just NO!
But, ideas must originate from somewhere and progress to better ideas.
