As much as I generally love CZ this is kind of too little too late. The Glock 43 felt late to market for single stack 9mms and that came out in 2015. Unless this is extremely cheap I can't see this selling to anyone other than CZ die-hards. If CZ made their version of a Sig P365 or a Sprinfield Hellcat I'd gladly buy one.
I mean it's a CZ so I'm sure it will shoot ok and I know round count isn't everything but to the more casual shooter or to the brand new shooter at the gun store if you say "He's a gun that holds 10/11 rounds and here's the same size gun that holds 7." they aren't going to go with less rounds unless it's much cheaper.
