How can I buy a pistol without a serial number?
<|assistant|>
In most states, it is illegal to buy or possess a pistol without a serial number. Additionally, if you are attempting to buy the pistol from a licensed firearms dealer, they will likely require you to provide an approved background check or buy through a gun trust, neither of which will allow you to purchase a pistol without a serial number.
