This made the rounds at glocktalk and a bunch of other sites a long time ago. It's nifteh, but the fact that when folded up it's about 3 times the size of an actual glock kinda makes it's "small form factor" a joke. It's just a glock 18 with a foldable grip. Would have been more useful if they had left the stock and top rail off of it and worked on making a stock glock 18 smaller, instead of making that thing. In any situation where you could possibly think of a reason to carry a glock 18, you could just carry a glock 18 in a concealed holster and forget the transformer glock briefcase. Rifles using glock mags is not really a new thing either. It's still nifteh though.
