I can't seem to find the post now, but earlier today someone posted a link to a site that identifies guns used in particular movies. It got me wondering... who owns all those guns? Are they just in prop shed somewhere? How are they able to use/have them in Kalifornia?

For example see the link to Terminator 2:
http://www.imfdb.org/index.php?title..._Judgement_Day

It shows them firing the real thing.
