The thing is, if you were to sell it to the guy in El Paso, and then he and the CA guy worked out something between them, you would not have broken any laws.
Non-Californians get all haired out about the CA laws. But if a Californian imports a gun or magazine illegally, the Californian is on the hook; not the non-Californian. Furthermore, the state of CA does not have jurisdiction over the non-Californian; only over the Californian.
See, this is what the anti-gunners in CA want. They want to instill unfounded fear in non-Californians so that business just flat-out dries up.
I am a CA lawyer, and I specialize in gun laws. Over the last few years, I have encountered numerous situations where the CA DOJ actively misrepresented the state of the law to the private individuals (and guns shops and distributors) in order to further the CA anti-gun agenda. It is thoroughly disgusting. And it has created a situation where non-Californians don't even want to do business with Californains, even if that business involves a perfectly legal transaction.
An example is the following: When I was in Vegas a couple years ago, I walked into a gun shop and tried to buy some high-cap Glock mags. Legally speaking, once I leave the borders of CA, I can buy all the high cap mags I want. I just cannot bring them back into the state with me. Well, the gun shop refused to sell to me on the ground that I was a CA resident. They told me that the CA DOJ had contacted them and told them that they could not sell high-cap mags to CA residents. This was a blatant misrepresentation of the law by the DOJ.
Another example: I like to shoot Saiga AKs (the variants imported by RAA). These are perfectly legal in CA and I have bought several in a local gun shop here that pushes the envelope on what we can legally own (thank God for their courage). A couple years ago, I contacted Gilbert's Guns back east and wanted to buy several Saigas. They told me that they could not do this because the CA DOJ told them that these Saigas were "assault weapons" and were banned in the state of CA. Another blatant lie by the DOJ, with the ultimate result being that an otherwise legal transaction has just come to a screeching halt.
The CA DOJ is reaching out to non-Californians (over whom the DOJ has no authority and/or jurisdiction), leaning on them, and misrepresenting CA law in order to further the anti-gun agenda. The DOJ is meddling with interstate commerce, even when that commerce involves a perfectly legal transaction. Talk about gestapo.
I see all the time on Gunbroker: "No Sales to CA." Guess what. When this kind of attitude takes hold, the anti-gunners have won. It is exactly what they want.
PLEASE, if the transaction is legal, send the guns to CA. Make a stand and shove it down the anti-gunners' throats. Push the envelope.
