Your 19 sounds likes it's as reliable as my 3 CZ's...Or my Shield.I have never owned a CZ pistol, but have handled them.
With their inboard slide and most ergonomic grip, they feel, and look awesome!
But I am in love with my constant companion, the Gen 4 Glock 19. That has never failed to feed, fire, and eject. So will continue to admire the CZ from afar.
Haven't all your other pistols have been as reliable as your g19?
Reliability isn't a unique to glock trait.
