Web...I say make yourself happy!
Personally I like a tried and true design. A derringer. Get them in a good sized calliber...9m or 45. Watch out for the recoil. But at close distance it wont matter. You will always be accurate at 3 feet or less. At that distance if you need an extra shot its ok.
WW11 FN Browning Hi-Power 9m, F.E I. 22lr POS revolver, Sig Mosquito 22lr SA, Taurus 94 22lr revolver. My next gun.....357 magnum revolver or 45 ACP SA....so many choices so little time...hey show me that great big shiney one.....hummmm....looks like my wallet just got several bills lighter..
