Thanks for the comments! As with others I must say I am really impressed with these VZ grips. In holding some polymer framed firearms afterwards they all seem slick by comparison, though that's not really true.
I know I can get factory direct mags from CZ, but my past experience has left me with nothing but warm, fuzzy feelings for Mec-Gar so I will likely just go that route.
By the way, while minor it was nice to see that CZ has updated its boxes from the old black plastic with plain egg-carton padding.
