I don't hate Glock, after all I have one and shoot it often. There are better handguns out there for the same price. I personally think Glocks are overpriced for what you get. Ill give ya a list of why.
1. The barrel, the most important part of the gun. The chamber is not fully supported, which ticks me off cuz I reload. But, the worst part of the barrel for me is the STUPID polygonal rifling. I hate it!!! It's less accurate than button rifling and doesn't cost any less to do. So you can't shoot lead cast or reloads in a Glock, that's half the ammo I shoot!!!
2. The parts in the lower are CHEAP sheet metal, after that they are just sunk Into the polymer of the lower. If S&W, Springfield, and Beretta can use full steel parts, why can't Glock?!?!
3. The triggers suck. They break like a green twig.
4. If you are used to shooting ANY other pistol you will hate the grip angle. Its angled in such a way that you have to hold it like a limp-rested fairy just to shoot it!!
All in all Glocks arnt bad guns. If new Glocks sold for more around $450 they would be awesome.
