Depending on the model and age, different places. All are marked as to where made.
MOST handguns do not have an option of a stock. In most cases, adding a shoulder stock to a handgun is illegal under US law unless it is registered with the Federal BATFE as a "short barreled rifle" and a $200 tax paid on it. There are a VERY few exceptions to that law- certain Mauser, Luger, and Browning pistols.
