the CX4 is stupid accurate, doesn't misfeed, and has excellent ergonomics despite the outward appearance.
my 9mm flavor uses ubiquitous 92FS mags, which are available by the railcar under normal societal circumstances.
IF i didn't have a AR pattern carbine in 5.56 close by, and IF i didn't have a 1301 tactical w/00-buck close by, i would not hesitate to pick up the CX4 and put it to work.
that said, here is where i probably rile a few feathers: it is an excellent "long arm" for my wife.
it's compact enough for living room MOUT, it points easily, it has a rail for a light, the manual of operations is easy, and 124gr +P Gold Dots emitted from a long barrel provide reliable "hey stop that behavior" feedback to people and zombies alike.
what it doesn't have is 1) the stout kick of 12ga 00-buck, and 2) the "holy fuck" factor of shooting an unsuppressed 14.5" 5.56x45 indoors.
