Nor did he foresee that guns even smaller than in his day would be chambered in 9mm Luger. Also, how could Carl Walther know about future +P ammo, and that tilting barrel pocket guns would not be rated for this ammo because shots would go wild due to the barrel unlocking before the bullet had left? Just because someone in the past said something couldn't be done or wouldn't be practical, doesn't mean that someone in the future can't figure it out. The Boberg XR9-S pistol is proof.

Carl Walther´s team did a lot of research on this matter before coming to the PPK design, rejecting this design, because of complexity and not that much better after all.

As much as conventional systems have problems feeding different types of ammo and different loadings, I imagine this would have even more problems, especially since it will likely require a shorter COAL. The weak/limp wrist issue can be negated by a lighter spring, just as it is in lower pressure/power catridges. As for the timing issue, if sufficient room is allowed so that the timing can accomodate the lowest and highest power loadings, it shouldn't have the timing problems I suppose Crypto is alluding to in the M2. This is the first I've ever heard of this firearm and so we'll see hwere the company goes from here. Looks pretty novel to me. I think is is great, but I can see where the problems will lie.

Yes the chanber has been moved back significantly, but it's also devoloped this huge growth on the back end. Overall length seems about the same for such a huge increase in complexity.

Too many moving parts to be totally reliable. The backward and then forward motion of the bullet seems to me that the gun will jam more often than a conventional automatic, especially from a shooter with a limp or weak wrist. A conventional auto just pushes the bullet up and the slide slams it home. Jams occur with the same wrist weakness but are limited to the barrel and slide making it easy to clear a jam. If this happens because of the lifting mech, it would seem that the gun would need to be dismantled. You also have an extra spring for the lifting mech as opposed to a genuine blowback design. Springs tend to be problem areas It seems to me that the lifting mechanism is the weak link. Too many moving parts to be totally reliable.

I wonder if it's going to have chronic headspace and timing issues too? This action reminds me of a flipped-over M2 machine gun.

Getting full-size performance out of a compact gun means better expansion with hollow-points.
