My initial impression is that the recoil looks very harsh. Assuming they are shooting birdshot in the initial few clips, they are getting rocked compared to what I’m used to seeing with my Remington 870. Additionally, they say that the two mag tubes hold 7 rounds a piece (nice!), but you have to switch between the tubes manually (Booooooooooo!).
According to Kel-Tec’s comments on youtube, the cheek plate is metal. Seems like an odd choice of material considering getting a cheek weld in a cold environment would likely result in a piece of your cheek taken with it when you un-shouldered the gun. Hopefully they coated the metal in plastic to prevent that (I can’t tell from the pictures) … it would be an easy fix.
