The .357 Magnum is a revolver cartridge based on the .38 Special (previously a popular police cartridge) and was developed in the 30's so villains couldn't hide behind car doors during shootouts any more - this bad boy would just go straight through!
There are a couple of notable weapons in which you'll see this cartridge, the achingly beautiful Colt Python and the utterly mental COP 357 Derringer - follow the links to find out more....
If you're looking at this site wondering which calibre to go for as you don't care much for the history behind them and just want one that looks awesome, this is the one for you. It's a great size and just looks..... cool. You won't be disappointed.
There's plenty of space on the 30mm length for up to 21 characters per line, so get customizing!
