My bet is CZ is experiencing some serious trouble. Hope they can right the ship.
I highly doubt
the company is experiencing serious trouble - though they may be having technical trouble with getting the webstore re-established. The old webstore was really archaic, and I'm sure it was a pretty big project to modernize it, having done some of that work myself.
Regardless, the webstore probably isn't CZ's highest priority. I bet their webstore has never really generated all that much revenue, comparatively, given that many aftermarket parts and accessories that people most want are available elsewhere. I'm sure CZC and CGW have become the go-to source for many parts and accessories, and as we all know, many of their replacement parts are actually improvements over OEM. All of that no doubt eats into CZ's own webstore sales.
CZ's primary focus is manufacturing guns and getting them to distributors. And given the unprecedented demand this year, I'm sure that's where a lot of their effort is going right now.
