Not DA it isn't. That's still ruled by CZ, who does a passable job with SA only as well, and it's trivial to convert modes.
But really, a polymer, safety, hammer-fired gun? Doesn't that sound like the CZ P07 and so forth? Just without the 42 years of design improvements?
Not interesting to me personally, but whatever.
I'm not interested either. It won't be the first polymer, safety, hammer fired gun, and even if it were, I still wouldn't be interested.
You didn't mention DA.
