Glocks are dependable and unexpensive that is why they are so popular. Even though I am not a huge fan of Glock I will say that they go bang every time the trigger is pulled and they shoot accurately. I owed the G21 and had Trijicon sights on it and there was nothing I could complain about it although I sold it to a Deputy Sheriff that dug it because of the night sights. Glocks are light on the hip compared to other like size firearms so when carrying it all day on a duty belt along with other equipment, weight becomes a huge issue. Personally I would choose a CZ over a Glock but that is just a personal preference as I believe the CZ has one of the best feeling grips out there and even though I am younger I love the feel of an all metal frame. As to seeing a Glock coming completely apart, that would have to be something I would have to see to believe as i have had several friends that have owned Glocks and having owned one myself I have not seen one have even one failure at all. I have heard and read about G22's in the past blowing up because someone shot lead bullets through it and not jacketed which the owners manual states should be the only type of bullets shot through them.
