Records, documents, gun issues....
Here are some random points re; firearms & legal-document-property issues;
I'd join the NRA
www.nra.org & get a firearm insurance policy for your property. This may be better than your current plan or be easier to deal with.
I'd keep track of or retain any sales records(warranty cards, sales receipts, FFL forms, owner's manuals, etc). Note the weapons serial #(s) & take a few digital images too. I keep my duty/carry gun details in my cell phone in case it's stolen then I can immediately provide the information to sworn LE if it's stolen or I get into a critical incident.
Some forum members may say; hey so what! But I recall watching a street bum run up and grab a guy's smokes, lighter & change off the ground as he was being put under arrest by 2 plain clothes deputy US Marshals!
Don't think that in a serious use of force event, you can drop your weapon or gear(white light spare magazine folder knife etc) down & no one will snatch it.
I'd only use factory made rounds for duty or protection & save 2/3 in the container or box just to document when the ammunition was made or if it could be tested for ballistics. Author & legal use of force instructor: Massad Ayoob suggests this to armed citizens.
Keep your firearms clean & check them often to make sure they function. It's safer for you and looks better in any court/civil actions if you use it in a critical incident. It will help maintain the firearm value also.
Read the firearm owner's manual & be aware of any special instructions re; cleaning or it's use. If a criminal investigator or lawyer asks if you read the manual you can honestly say; yes.
Save the records or documents from any training classes or seminars related to your weapons.
