Will hand guns purchased legally become targets due to a paper trail? If so will your home be searched? Am I to go on the run, no one is taking what few guns I have.
Not all legal
sales result in paperwork. It is perfectly legal under federal law to buy used private party (non-FFL) weapons without any paperwork. Some states do not require paperwork either.
It is also legal to go into a foreign state and buy a used private party firearm, however there are a ton of conditions that must be met in order for this to occur.
1. you must not lie about your residency if asked. It is illegal to do so.
2. They must not ask. There is no legal requirement for them to ask.
3. the gun must be an ordinary firearm and not something exotic or NFA listed
4. the gun must not leave the state you bought it in, which means you legally cannot take it home. It becomes illegal when you transport it across state lines - any state lines even if its not home.
5. the state you buy in must allow for paperless private party transactions
6. the state you buy from must not have a law that specifically excludes out of state people (surprisingly this does exist)
All of this is written in 18 USC 921 (definitions, particularly where interstate and foreign commerce is defined) and 18 USC 922 (the actual statutes that define what is and is not illegal).
This has limited use because you cant take the weapon out of the state you bought it in. I see this method only useful if you either visit that state a lot and do not want to be bothered with the transport of firearms (which you legally cant do on some methods of transport although airplanes are ok just no ammo and some other rules). The only other use I can see is if you have a bug out location in the state you buy and you are afraid there may be weapons checkpoints between where you are and where you are going. Having them there beforehand would ensure you have something when you arrive, providing it is properly secured to avoid anyone taking it.
