I cannot tell you if a gun is safe to shoot from WAAAY over here- but there may be some things that would make me tell you it is UNSAFE to shoot.
For a few bucks more, with some careful shopping, you could find a decent Stevens 311- something like THIS: http://www.gunauction.com/buy/10984680/shotguns-for-sale/side-by-side/stevens-home-defence-model-311-.16-ga-with-18.25-inch-double-barrels
It will need some cleanup, some Formby's Refinisher and some linseed oil for the stock- but those are DIY sort of things.
Besides the purchase price, you need to add shipping, and the fee that your dealer will charge for recieving it and transferring to you. That seller has decent feedback, and there are other guns on auctionarms and on gunbroker.
