Just returned from SHOT where I played with the new Keltec shotgun too, and I noticed the exact same thing! The trigger would not reset!! You had to be completely off the trigger when cycling the action. Wow, I really do hope they iron that out before production.
Another concern with the weapon is that we all know how important loading is to running a shotgun. The mag tubes are buried way up high in a chasm in the rear receiver. You'd have to be a veteran proctologist to load this thing quickly. Shoot 14, then discard and transition...
Must say it was a big hit, lots of traffic in the Keltec booth.
Also hoping they will fix the trigger issue.
Thinking from a home defense situation, this could be ideal. 99% of the time you are not going to have extra ammo on you in a home defense situation other than what is on the gun. This gives you 14 shots at the bad guy, most of the time you should not need more than that. Find a way to throw a side saddle on it and you have even more ammo. Plus it is short and easy to manuver. imho.
