The Dragoon is now a collectible arm and sells for high prices.

Non-firing replicas of the Colt 1848 Dragoon were manufactured at Denix in Spain.
In 2005, a fire burned down the factory and destroyed the mold for the gun, which has since gone out of production.
Denix has since reintroduced the non-firing model of the Colt 1848 Dragoon in Nickel.

Quality Replica Dragoons are currently produced by the Aldo Uberti Company of Brescia, Italy and distributed in the United States by Taylors, Inc.; Cimarron Firearms, and others.
They are quite accurate and potentially more powerful than the belt sized revolvers of the same bore diameter.
Velocities with .451–457-inch round balls of approximately 141 grains over the full 50 grains of powder frequently show chronographed readings in the 1,000 to 1,100 foot per second range depending upon the powder used.

A cartridge-converted Colt Walker instead of the Colt Dragoon in the book was used in the 1969 film True Grit, as the weapon carried by 14-year-old Mattie, possibly due to the Walker's larger size.
The Dragoon was used in the 2010 Coen Bros. movie as in the original book.

In Lonesome Dove, by Larry McMurtry, Captain Gus McCrae is armed with a Colt's Dragoon revolver.
In the television adaptation, Gus is armed with a cartridge-converted Colt's Walker revolver.
