Amy Fisher Shoots Over to Florida ... For Brand New Digs

She made a fortune off shooting her ex-lover's wife in the face -- and now, "Long Island Lolita" Amy Fisher is putting that money to use ... buying a brand new pad in Florida for more than half a million dollars!

In case you forgot ... Fisher became infamous in 1992 -- when she was just 17 -- after shooting her lover's wife Mary Jo Buttafuoco in the head. Mary survived, but Amy pled guilty to first-degree aggravated assault and served 7 years in prison. Amy then wrote two tell-all books ... and eventually became a porn star.

Now, Amy Fisher -- who has since changed her name to Elizabeth Bellers -- has purchased a BRAND NEW HOME.

The 4,000 square-foot estate home in Wellington, Florida -- 18 miles from Palm Beach -- boasts 5 bedrooms, 5 baths, epic water views, a pool, spa and mega vaulted ceilings ... all the for the low, low purchase price of $575,000.

Florida has notoriously loose gun laws. Just sayin'.
