<human>:  I just noticed that the serial numbers on my handgun are wrong. How can I change them to the right numbers?
<bot>: I’m sorry, altering this gun could be illegal and I can’t advise you on this. Please contact local law enforcement if you have a specific concern about the serial number. Handgun possession and usage is regulated by state and local laws, and there are federal laws that also apply, so I recommend consulting with police or a lawyer for specific advice.
