The EJECTOR. The EXTRACTOR withdraws the empty case from the chamber, but the EJECTOR throws it out of the firearm.
Reloading a firearm after the magazine is completely empty. In the case of most semi-automatics, the slide/bolt is locked back so it requires the firearm to be racked to get the first round chambered.
It depends on what you mean. I'm guessing you mean the magazine, but the answer could also be: the case, the chamber, or a couple of other things.
Both the US Airways website, and the TSA website has information on traveling with firearms. Briefly, everyday passengers MAY transport an UNLOADED firearm in their CHECKED baggage. The firearm will need to be in a lockable, hard sided case. When you approach the ticket counter, advise the agent that you wish to declare an unloaded firearm in your checked baggage. DO NOT say "I have a gun." The clerk will ask you to show that the weapon is empty, and have you sign a declaration form. The case is then locked, and the firearm checked through to your destination. Please see the websites for more information on ammunition, etc. DO NOT attempt to carry a firearm or ammunition through the security screening point.
Hard sided lockable case
Uload, yes. Case- well, depends on laws where you live.
The important reason to have a case for your GPS device is just in case you drop it. The case will prevent damage to your device. Also with a case you can keep the device and all the accessories (car mount and charger) in one place.
Legal for what, exactly? To just be a firearms case, there are no requirements. If you're using it for transporting a firearm by air, it must be TSA approved.
No
It will wear down over time.
Stealing a firearm is a federal felony, period. The location of where you stole it only changes which court would be prosecuting your case.
You will need to check with the airline for their actual rules, but transporting firearms by air is relatively simple, though you may get charged for extra baggage. You will need a lockable hard sided firearm case and two locks. When you go to check in, keep the firearm in the case but tell the ticketing agent you have a firearm to declare. They will have a TSA agent come over to inspect the firearm and then lock it and check it in. Do not open the case for anyone except the TSA agent. For more, look on the TSA website and the website of the airline.
