If you don't own a Glock or have limited experience with them, I suggest you refrain from commenting, less you wish to be the fool. Wait, you already proved that point above and below. Cast lead in a stock Glock barrel will void warranty, it can be done, it is done by many a Glock users. If you watch your round count and monitor the "leading" of the barrel, its entirely a non issue.
Your post is so full of bullsh*t I can smell it through the screen. Glocks have a non forgiving trigger, as in, learn to apply the fundamentals or you won't hit sh*t and will look like the untrained uneducated novice you are. The chamber specs on a Glock are not "loose" as you say, they're per 9x19mm NATO/PARA specs. Reloading brass is fine and can be done many a times. I personally know a guy who's been running lead and reloads through his G19 for close to 15 years. Some brass is over 5 year old.
Glocks are not "perfect" as so many Glock haters seem to believe the pro Glock crowd promote. The reality is that Glocks are as close to perfect as has been produced to date as far as service pistols go. There is very little for Glock to improve on but they have made improvements in shape as well as internal dimensions and parts. Externally you won't see much but the changes are there. Then again, for a guy who doesn't like them and likely doesn't own one its hard to believe you'd notice these change or believe anything you have to say about them.
The stiff magazine is intentional, it prevents rounds from popping out if you drop the magazine. Ten rounds isn't that difficult to load by hand. If your inability to load a stiff magazine is what you consider a reason to avoid Glocks, then you're looking at the wrong criteria.
