They've gotten better and better over the years and last couple years they been on par with Primary Arms for me with shipping speed which is pretty damn good.
I don't know if they updated the trigger but the ones I shot had the stupid false reset trigger that was mildly annoying and would definitely take time and effort to get used to if you are used to shorter reset triggers.
CZ polycoat is a a baked on polymer over a semi pakerized finish for steel guns. It's basically powder coat.
It's more durable than hot blueing. Compared to cerakote (which is just hard mechanically bonded paint) it's much thicker softer, and smoother. My P01 has a cerakoted slide and polycoat...
