Add Weapon on Enter?

Does anyone know a script where a player comes into a game, and automatically a weapon is placed in their inventory?

I want the item to be available for certain players

This isn't a script, but something many people don't know how to do. Here is what you do. Right click "Startpack" in the explorer tab. Then select add basic object, and select backpack. Then, click on backpack, find the gear you want, double click on that, and there you go!
