Beretta has made many different types of 22LR firearms. You will have to be a little more specific.
Contact Beretta Customer Service through their website. You will need model and serial number.

Some. I own a Beretta 92FS. It's a variation of the M9 used by the military. Both my gun and all M9s used in the US military are made in the US. However, you can purchase Italian made Beretta guns.
