A handgun carried into the Battle of Little Bighorn by a legendary U.S. Army cavalry officer is headlining a high-profile firearms auction in Bedford, Texas this weekend. 

The Colt single-action revolver belonged to Captain Myles Moylan, later a Medal of Honor recipient — and has an estimated price of up to $120,000. 

"It’s just an amazing piece of American history," Kevin Hogan, president of Rock Island Auction Co., told Fox News Digital.

Hogan, a lifelong Illinois resident, moved his 30-year-old company from his home state to the Dallas-Fort Worth Metroplex in December. 

He cited both more favorable business and political environments in Texas as reasons he relocated his company.

"The great thing for collectors," said Hogan, "is that you visit these eras, these times and these places though these objects that were there and played a huge part in major events. It’s very exciting."

MEET THE AMERICAN WHO FOUGHT AND BLED AT THE ALAMO BUT LIVED TO TELL ITS HEROIC TALE: SLAVE JOE

Captain Moylan’s Colt revolver from the Battle of Little Bighorn in Montana is the auction’s most exciting piece, said Hogan.

The officer’s legend is one reason why. 

Moylan fought to save the Union at Gettysburg, Pennsylvania during the Civil War in 1863.

He rode into Little Bighorn, Montana, with the 7th Calvary in 1876.

American troops under Gen. George Custer were decimated in battle by Lakota Sioux, Northern Cheyenne and Arapaho warriors.

Moylan survived Custer’s Last Stand, his Colt cavalry model revolver by his side.  

"The gun is not only identified with the 7th Cavalry, it’s also ID’d to Captain Moylan," said Hogan. 

The officer earned the Medal of Honor for heroism when he was wounded at the Battle of Bear Paw, a decisive victory in the Nez Perce War in 1877.
