Impossible to answer without more information.
About $225 used.
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.
used is about $225
100-300
100-400 USD
50-500 USD or so
400 in used but good condition
$300-$400 depending on condition and action-type. I bought a used Beretta for $350 that is Double Action Only. It is probably not as valuable as a full Double/Single model. I really enjoy my Beretta.
300 USD or so
Depends on which model Beretta, and what condition it is in. A like-new Beretta 92 with adjustable sights might be worth $500. The same condition Beretta Cougar might be $350. If either of them are rusty or nicked or scratched, make it $250 or so.
