A nice little surprise at the 2010 Shot Show was the Magpul Folding Pocket Gun (FPG). This thing is just plain cool... Start with a little black box, and in less than a second (and a flick of your thumb) you can deploy it into an SMG.
The Magpul FPG will first be released as a conversion kit, and is designed for the KWA/KSC 18C GBB Pistols. Some other brands/variants will be compatible using parts included with the kit, but full details have not been released yet.
The FPG has been in development in the Real Steel and Airsoft worlds for over a year. The design phase been long and difficult, as Magpul must not infringe on Glock patents with this product. As many airsofters are aware (and disappointed by!), Glock has been completely against licensing thier brand for airsoft. They are known for aggressively going after those making unlicensed clones. Magpul's FPG design has been engineered to accept a Glock slide and magazine without copying the mechanisms of the patented lower receiver. The carry handle/rail combination can be removed to allow the FPG to be stored easily. When attached, the weapon is deployed by flicking the charging handle with your thumb.
The rest is taken care of by the clever design... the stock and grip (complete with extended magazine!) unfold and lock right into place, making the FPG ready to fire As you can see in the picture below, Magpul has even designed the FPG's rail to accept accessories such as flashlights and lasers.
Collapsing the Folding Pocket Gun is a little more involved. The three main steps include folding in the grip (the mag stays in!), tucking away the foregrip, and finally closing the stock which will lock the entire unit shut. Once you run through this process a few times, it can be taken down in a matter of seconds.
Towards the end of this year. Magpul is looking to release a complete version of the FPG using KWA internals. Don't expect this sexy piece of kit to come without a heafty pricetag. Also, don't expect the hefty pricetag to deter you from needing one once you have experienced it!
Here is a quick video of a lucky bystander trying it out at ShotShow 2010. As this was the first time he held the FPG, it's very apparent how intuitive the design is.
Spartan Imports also made a sweet (and more fancily produced) video for the FPG that you should check out as well. Hey look, it can actually fire!
