My son-in-law went wrong with a Glock: the front sight fell off.
Well, that certainly proves that all Glocks are crap.
I can come up with anecdotes for any gun you can name, therefore ALL guns are crap.
I would not say he went wrong with a GLOCK. He simple needs to upgrade to metal sights. Factory GLOCK sights are plastic unless you get the factory night sights.
