May I ask what they were saying? I went through the same thing, as far as people complaining about them being "tight" and tending to malfunction in the first couple hundred rounds. The only thing I did was put on a Mechanix glove and rack the slide back and forth 150-200 times when I first bought it to "break it in." Sounds stupid, but the slide was VERY tight brand new and after racking it back and forth before firing for the first time, it has performed flawlessly and the slide is very smooth.
