Had a coworker today tell me he had 2 homicide detectives visit him over the weekend over a handgun he sold to a young female used in a shooting.

My coworker had his ass covered and provided the bill of sale w/ the females permit number, name, and he even had her cell phone number.

So just a reminder that when selling a firearm to someone you haven't met, it would be a good idea to keep some kind of bill of sale w/ at least a permit number to help law enforcement in the event the gun you sold was used in a crime.

That's good advice.  Oh and technically the law says the certificate is required for handgun sales and makes no distinction between retail or private sales...

Your coworker is really lucky btw!

Good info. Thanks!
