Key Features

• Authentic Henry Nettleton Inspection Stamps – Every stamp matches the original 1st Generation Colt font and placement, making this a true collector-grade piece. Why it matters: You get the exact look and provenance of a $10,000+ original without the century of wear.
• 7.50″ Blued Steel Barrel – The iconic Cavalry-length barrel delivers the classic balance and sight radius of the 1873 model. Why it matters: Longer sight plane means better accuracy at the range, and the blued finish resists rust better than the originals.
• Color Case Hardened Frame – The frame is heat-treated for a rich, mottled color that deepens with handling. Why it matters: This is the same process used on the 1st Generation Colts, giving you an authentic patina that only improves over time.
• Walnut Grip with Exposed Hammer – The one-piece walnut grip fills the hand naturally, and the exposed hammer allows for single-action precision. Why it matters: You can thumb-cock for accurate shots or shoot double-action fast—your choice.
• 6-Shot 45 Colt Cylinder – The classic 45 Colt chambering packs enough punch for hunting or defensive use. Why it matters: 45 Colt is still widely available, and the 6-shot capacity gives you plenty of firepower for plinking or competition.

Who It’s For

This revolver is built for the collector who demands historical accuracy, the cowboy action shooter who wants a competition-ready piece with provenance, and the gun show enthusiast who loves telling the story of Henry Nettleton’s inspection marks. If you own a safe full of modern pistols but crave a genuine piece of 19th-century American history, this is your revolver.

Pros & Cons

• Pro: The Nettleton stamps are applied with the exact same font and placement as the originals—verified by Cimarron’s own research.
• Pro: The 7.50″ barrel gives you a sight radius that makes 25-yard groups tight.
• Con: The color case hardened frame will show a slight color shift with heavy holster wear—that’s a feature for collectors, but if you want a pristine safe queen, consider a blued model.
