I can hit the orange.
Nope.
They can take it and run the serial to check stolen, but the only way they can take it and keep is if it is evidence in a crime. IE, you are in handcuffs.

I keep the bill of sale in the glovebox for my truck glock every other gun was bought by me and yes a LEO checks it against the NCIC to make sure it was not involved in a crime or stolen or you just shot your babies momma with it
