Let's not forget that Glock has been top dog for roughly 23.5555555 years and their latest run for perfection lobs brass like grenades to the face. No gun is perfect, every gun is unique. If it is a problem, the question is how well and how fast will CZ correct. There is no perfect gun, rifle, shotgun,.....:Gasp..... Customer service is King. Having a issue is not always a bad thing. It allows the customer to see how well the manufacturer takes care of the problem. Just my 2 cents.... Ok boys letter rip... Lol.... One question not asked was did the ammo pass the plunk..... Was it 115,124,135,147??.
