Where do you find the hand gun in Resident Evil 3

now this is either a really stupid question or you just wrote it wrong

there are handguns in re3

the standard handgun you start with it at the begining of the game automatically

then there is the desert eagle (handgun but some people argue that it is a magnum) but in re3 it sounds and looks like the handgun and uses handgun ammo but in other re games it does seem like a magnum

now i assume you meant the desert eagle which is the gun i think you meant you get it by defeating nemesis in the police courtyard and the second battle (forgot location) anyway after defeating nemesis he drops a package called desert eagle part A then after the second battle he drops desert eagle part B combine them together and then you have a desert eagle (uses handgun ammo)

if you didn't mean those 2 guns then you must have be more specific
