I've owned Glocks since 1990 and while, in recent years, I have found pistols with better ergonomics (at least for my hands), I will say that Glocks are solid pistols that do shoot relaibly. There is a reason why there are so many of them out there. And, of course, when there are millions of anything out in the world, you are bound to find a few that have problems.
If you don't like them, then don't buy one. Buy what you like. No one can force anyone to buy a Glock.... I don't understand why some people waste so much time and energy putting down something they don't even own. Time better spent out on the range shooting whatever gun they do like....
