As has been mentioned, each has its advantages. I do not agree that the Glock trigger isn’t made for accuracy. Although the trigger may affect your ability to shoot a gun accurately, it has nothing to do with the inherent accuracy of any firearm. Well, most anyway.
I like the Glock because it’s tough and built for abuse. The trigger you can get used to or modify it to your taste very easily and without compromising the reliability. I can hit clay pigeons at 25 yards pretty easily. The Glock also presents a profile and operation that is easy to manipulate during high stress situations. A slide that you can get a good grip on. Easy controls. Etc. You draw and it’s ready to go.
With the beretta, I never could get used to that long trigger pull on the first shot and it’s usually the first shot that’s gonna matter the most. I also question the durability in comparison to the Glock. Ever google “useful life of 92F frame?” Of course, berettas exhibit a smoothness that few can equal. That ejection port makes concerns of ejections problems moot. I’ve also never known a beretta to have a feeding problem. I know guys in law enforcement that describe it as a fine weapon.
Most of my experience with the CZs has been with the steel guns, but they are representative of all models that I’m aware of. Again, I couldn’t reach, much less get used to, getting that first round off with that trigger. I also find it difficult to manipulate during drills. With the inverted rail system they use, the exposed portion of the slide is short and difficult to rack for me when my hands are sweaty or I’m wearing gloves and I’m in a hurry. On the plus side, they just plain work. They have a fan base and it is warranted.
