The Magnum is a gun you can find in zombie survival game, Project Zomboid. (First revolver, yay.) Now then, sit down for this one because the Magnum is literally the best handgun in the game. It has the highest MINIMUM damage of all guns, and tied for max damage of all guns with the D-E Pistol. It has the highest stopping power, the highest range, and literally cannot jam. It is more common than the D-E pistol (If you gamers want a tip on where to find it, check farms ;D ) and usually comes with more ammo than the D-E pistol itself. It uses .44 Magnum ammo (Obviously...) which is pretty rare. But, aside from the good, heres the bad. It is the loudest handgun of all, having a detection radius of 80 tiles....thats a lot of tiles. The reload speed is slower than most pistols (which use mags, you have to load the revolver with each individual bullet.) And also is tied for 2nd least accurate pistol (With the D-E pistol. WHICH IS WAY YOU LEVEL AIMING.) But if you really put in the effort and level aiming, this gun is crazy good. (Also it can only take iron sights and red dot. Sad D: )

It can be a person being magnum which means being really cool or it can be used to describe a time or object which would mean it was fun or great.

Typically means a condom beand. But we are using this as a form of short and weak man who sits around playing games all day in his sweaty room.
Digito: man you are being such a magnum today. Go touch some grass.

A person who buys condoms that are way too big for him.
Person 1: OMG Seth is such a magnum! Did you hear that he bought a box of XL condoms when he barely fits an XS.

Person 2: I know! My pinky is bigger!
