Do you think people are buying pistols from guns shops and neighboring states and bringing them to California? How about rifles that are illegal in California. Are people buying those at gun shops in other states to?
Most people reading this far are probably thinking “Yes” because people don’t know shit about gun laws.
When a dealer sees an out of state license, they have to apply the laws of both the state in which the gun is being sold AND the state in which the buyer resides. When I sold guns in Texas and someone came in from New Jersey to buy a rifle, I had to do a New Jersey background check, run their Firearm Purchaser ID, etc on top of our usual process. I also had to make sure the gun I was selling them was legal in New Jersey.
Oh - and handguns can’t be transferred to an individual in another state. Period. If someone from another state wantred to buy a handgun from us, we had to ship it to a licensed dealer in their state to complete the transfer. The only exception is for federal Curio and Relic license holder buying an antique pistol that’s been unaltered (e.g. a C&R collector buying an authentic WWII German Luger).
Ammo: sure. People can buy that out of state easy enough. And I don’t see a problem with that. The person who wants 5,000 rounds of 9mm wants it because they are practicing. If people are going to own guns, they should be able to afford to train on them enough to shoot in a straight line, which is way harder than a lot of you non-gun folk seem to think.
And I’m way less-suspicious of the guy who wants 5,000 bullets than the guy who wants 5.
