So /k/ out of curiosity, how easy would it be to buy a small handgun in the eu then just catch the ferry from france back to the uk?

Every time I've been abroad by ferry I've never been searched at either end.

Would it be easy to buy the gun itself without a license too in some shithole country?

Just to re-affirm, I don't need or know anyone that would actually need a gun, can't think of any reason other than pest control a middle class whitey in full time education would
