Congratulations on the new Sphinx
............and the new Glock!
You'll have to let us know how they shoot for You!
As for your Cz100, the closest I've ever been able to come to that, is my S&W SW9VE, which does have a different Grip Angle, but a similar Backstrap.
I've been carrying the SW9VE most of the Summer and plan to keep carrying it on into the Winter.
I have become more accustomed to it's DAO Trigger and have removed that horrible pigtail rebound spring, which makes the Trigger now equivalent to the newer SD9VE's.
I'm considering having the Slide Cerakoted flat Black.
