Hey guys, I'm looking for any gun enthusiasts to help me out. Marty Robbins awesome song has inspired me to seek out "Big Iron" in the wasteland.

What would be the closest new vegas approximation of it?
Here's the Wikipedia description of the real world gun:

The Ranger's "Big Iron" actually existed. It was a one off custom handgun chambered in .45 Colt and featured a Great Western copy of the Colt Single Action Army frame, Colt 1860 Army backstrap, grip frame and grips and a cut down 9 1/2" Marlin rifle barrel. Marty Robbins saw it in Andy Anderson's famed North Hollywood gun shop in the late 1950s and wrote the song around it. Its current whereabouts are unknown.

Well here is a list of all the weapons in New Vegas ==> http://fallout.wikia.com/wiki/Fallout:_New_Vegas_weapons

My guess would be http://fallout.wikia.com/wiki/Ranger_Sequoia is the closest.

Yeah Styles has it right, A hand gun chambered for 45-70 rifle rounds

Sweet thanks for the quick replies
