Bigghoss, there is a You Tube guy named Nutnfancy who has done a video on the KSG and the PMR30. They are "extensive" enough I think. My general impression is that the firearms are adaquate, but have some teething problems.
The PMR, while an interesting concept, gives up too much in terms of velocity to make the .22 WMR chambering worth having. Now if they make that little carbine instead it might be getting somewhere.
The KSG is a neat little novelty. As a 7+7+1 shotgun it would have a very fast reload on hand compared to the conventional pump. Being a bullpup and naturally having to load it as it is designed it will be cumbersome and prove to not be so ideal. It is so short that you will want a vertical for the forearm to make cycling the action more effective. Once you have that fore grip, along with the pistol grip, it becomes bulky and even more cumbersome. After that and some other add ons it will have enough protrusions to hook and snag on things like a polymer burr. What it saves you in overall length it loses in added bulk. Seems to be the problem with most bullpup designs as it goes.
While it may seem to be really cool shotgun it just seems to be something that will not be that is cracked up to be. If they made it to accept magazines instead of using twin tubes it might be better in the reload department. On the other hand, can you imagine handling a magazine that wide and huge overall?
It would have to sell for $500 and come with a fore grip and sights to be even worth considering as a pump in my book. Even then it would be limited. If it was a semi auto it would be much more appealing at $700+. Even then the manual of arms to reload it is a real detractor for me.
It is a neat idea and Kel Tec sure is making some interesting designs and they should be commended for it. Other than that, the typical pump has a bit more going for it compared to the KSG. While the 7+7+1 brings a lot of "fire power" to start. It will fall behind after that as a fighing gun.
Just imagine stuffing it with 14 rounds and having to flip levers back and forth to do so. It becomes complicated in a way that isn't appealing as a fighting shotgun to me. Not to mention that firing a few shells and topping off will be not so efficient and loading through an ejection port is not even an option. What you gain in onboard ammuniton you lose on the other end of the spectrum.
Some may argue that the other tube would allow the user to have slugs on tap in a flash. That may be true, yet it won't be so easy to get back to shooting buck shot in the other tube. It would be training issue for the most part though. Still it adds steps that just make no sense if you subscribe to KISS, YMMV.
For those that find it appealing and can tolerate those little flaws it will be a great shotgun, provided the minor teething problems it has are solved.
Yet another Nutnfancy sized post completed.
