Rebecca and Billy both start off with a handgun in Resident Evil 0.
It might be weaker compared to other weapons, but there's plenty of ammo and it's relatively easy to use, so a lot of people rely on it as their main weapon throughout the game.
Here's a tip for all you handgun lovers out there: When Billy uses the handgun there's actually a small chance of getting a critical hit, which carries the same damage as a magnum round, and can easily turn the tables at the most random of times!
It isn't something you can plan for, but next time you find yourself in trouble try pulling out the handgun, you never know when you might catch a break.
