These are the DotMatrix Ergo aluminum grips from Kummer (KMR Arms). They have the palm swell of the factory rubber grips and an aggressive texture. This company is in Uhersky Brod. What buyers of the CZ factory aluminum grips might not realize is that production of those grips are contracted out to this vendor. They have an English language web site (kmrarms.com) with additional accessories and some parts. They ship mostly within the Czech Republic and Slovakia. Outside of these two markets is on an individual request basis per company website.
