For me there's 2, my uncle owned them both, first was an Uzi, full not mini, that was a lot of fun to shoot, I was very surprised by how smooth it fired, almost no recoil, 2nd would be a .44 magnum with 9in barrel, now that thing had one hell of a kick to it, I was about 14 the first time I fired it, almost jumped right out of my hands.
