I realized that all springs on all guns have the potential to break and will break with enough use. But reading about the CZ 75 trigger return spring breaking at a frequent rate. Is this an overblown issue or is it a real concern so that in terms of the trigger spring cz's are not as reliable as other pistols. (Let's say a Glock or an m&p pistol). I'm only referring to the trigger return spring issue. I just bought my first cz75 and love the ergonomics and accuracy of it. I plan on using this for self defense applications and am wondering if I should use another pistol instead. It seems that the common consensus out there is you use CZ for competition and Glocks for self defense. Is this accurate? Is that spring that flimsy.. in this otherwise tank- like gun?
