Should have added this thought..some may already do this..but if you do not, I'd suggest you do.
That is, take photos of the firearms you own !
Save the photos on a memory stick / & on a computer.
if there's ever an incident of a stolen / lost /missing firearm, you'll have a picture of it.
I try to include the serial # in the pic..to show it is mine. Reason ? Insurance verification, in case of a claim ,
and it may assist Police in finding /tracking / returning (heaven-forbid) a stolen weapon.
Never could figure out why some block the serial # in pics..the pistol was sold to / is registered to me, no one can say...".hey, that is mine! "
I save firearms purchase receipts too, .. when purchased from an individual, ( I make a hand written receipt) as well as box store or online purchases.
I keep a notebook with my purchases, sales receipts stapled to separate pages, a page for each weapon.
I also record accessories added ( scopes / mounts/ grips/ gunsmith services done.. etc...( again, save receipts)
This makes it much easier if / when you may decide you want to sell a gun..to recall what's been added / spent on it
