The Rohrbaugh Company claims to make the smallest 9mm semi auto (The R9). There are companies that produce very small single shot 9mm pistols.
You will have to go to a licensed dealer.
No- and potentially dangerous if it DID fire. The 9mm is shorter (19.15mm vs 22.86mm) The .38 Auto is a semi rimmed case, 9mm Parabellum is rimless. .38 Auto has a maximum pressure of 26,500 psi, the 9mm 35,000 psi.
Depending on condition, $300-$400.
I suggest you look up your particular model in a reference such as "Gun Trader's Guide"
