From Wikipedia, Tom Sachs entry:
Many works from the show conflated fashion and violence, as with HG (Hermés Hand Grenade) (1995) and Tiffany Glock (Model 19) (1995), both of which were models made with Hermes or Tiffany packaging.
Although these sculptures were non-functional, another piece – Hecho in Switzerland (1995) – was an actual working homemade gun. Sachs and his assistants would make similar guns and sell them back to the city as part of New York’s gun buyback program (for up to $300 each).
