This site is one of the best I've found. There are several members on this site who have forgotten more about firearms than I'm likely to ever know.
Here are some other sites I'd recommend...
Down Range TV - Guns, Personal Defense and Shooting Sport.
Personal Defense How-To Videos, Articles | PDN
nutnfancy's Channel - YouTube
As for the Beretta, I don't care for them; but that has nothing to do with the quality of the gun. Guns are a very personalized choice. They will all fit and shoot differently. This is a good thing because everyone is going to want something different.
For myself if I'm looking for a composite handgun, I'll look at the Springfield XDm and Rugers.
Go put your hands on as many different pistols as you can, and you'll find something that fits you.
