Well, I will chime in here with a different view. First of all, the price is good, especially with the hi-caps.
That being said, I used to own a 3rd generation model 21 (.45ACP). I will say that I was overall less than impressed with the pistol. The plastic guide rod just looks to me to be a weak link, although mine never broke with about 3,000 rounds. Secondly, the factory sights just plain suck, and are also plastic. Also, Glock's rifling prevents you from plinking with cheap lead ammo for fear of the infamous kaboom. Lastly, the grip never really felt ergonomically correct in my medium-sized hands.
You hear a lot about people putting in after market barrels, sights, recoil springs, guide rods, and having trigger jobs done. Oh yeah - the trigger absolutely sucks too, and there is no traditional safety if that kind of thing matters to you. Now I can understand a person customizing his weapon to some degree, but it just seems that a Glock is not worthy of its reputation out of the box (replacement barrels? Come on!!!)
Just my opinion. If you have fired and like them, knock yourself out. Nomex suit on.
