Big Iron 

Big Iron: A firearm, specifically a revolver. Due to the thick metal used in creating old-style revolvers such as the Colt Peacemaker or the newer Ruger Blackhawk/Redhawk, and partially due to the weight of the weapon, they earned the nickname "Big Iron." This phrase became largely popular after Marty Robbins' widly successful gunfighting ballad called "Big Iron."

"No lone dared to ask his business no one dared to make the slip, the stranger there amoung them had a big iron on his hip"

Big Iron 

A colloquism from the American Frontier days, referring to a handgun with a long barrel, as mentioned in the Marty Robbins song, featured in the video game Fallout: New Vegas. It was the style of the time for many to carry shorter barreled guns, often with the front sight filed down or completely off, to aid in a faster draw. So, anyone carrying a long barreled gun was assumed to be confident enough in their ability to handle the gun they would trade the speed of a shorter barrel for accuracy of a longer one.

Watch out for the stranger who just rolled into town, he carries a big iron on his hip.

Big Iron 

A popular song by Marty Robbins about an Arizona Ranger that goes to the town of Agua Fria to kill a young outlaw nicknamed "Texas Red" that is terrorizing the town. Spoiler: he succeeds.

The song has been parodied many times on Youtube, with humorous edits that may or may not change the story of the song.

Some of the most popular ones include:

-Big Iron, but Texas Red wins

-Big Iron, but the ranger is after everyone

-Big Iron, but everyone is dead

To the town of Agua Fria rode a stranger one fine day
Hardly spoke to folks around him, didn't have too much to say
No one dared to ask his business, no one dared to make a slip

The stranger there among them had a big iron on his hip
