Western Themed Magic Item ideas

My party is going to be doing an encounter that is meant to be themed similar to a shootout from a Western. Some bandits are assailing the town and the party is going to help fight them off. 

I was thinking a cool way to reward the party would be for the sheriff to award one of the party members his badge as a token of the help and protection they offered. I want to make this badge be a magical item, and was wondering what effects/reflavoring might work for a sheriff's badge. I am trying to think of magical effects that would thematically fit with a western sheriff. Maybe something like the ability to cast Command. Or perhaps it offers some sort of bonus to ranged attacks. 

I am posting here because I wanted to hear what ideas others might have

Well, sometimes a badge is also called a “shield.” You might riff on that.
