Certainly, and I'm not saying they shouldn't build it, I'm just confused about who they built it for.
I'm tracking on the magazine as the source of many of the design decisions. That's pretty obvious, but also a strange choice. A P90 mag is nicely designed, and works well, but it's not like a Glock mag that is approaching universality, or a G3 mag that has millions out there in surplus for less than $10. It's a bulky, hard to carry, $40 magazine.
And you can't even pistol brace this gun, because there's a charging handle where the brace would need to go. I guess on the plus side you could just 3D print a stock/grip clamshell and replace the whole bottom of the gun pretty easily.
I know I sound pretty down on this, and I don't mean to be. I like new things in the gun space, and I normally find Kel-Tecs ideas interesting, even if the execution often lacks. I'm just confused about the designer's vision for this gun. Are a lot of people finishing mag dumps on FiveseveN's and saying "man I wish I had another 20 rounds before the world's most awkward reload!"?
It's like someone left a Whitney Wolverine in whatever goo created the Teenage Mutant Ninja Turtles.
