Product Overview

The Cimarron 1878 Coach Gun 12ga 20" is a side-by-side double-barrel shotgun built on the legacy of the working guns that settled the American frontier. Where settlers, ranchers, and express messengers needed a firearm that could handle close-quarters defense and hunting with real authority, the coach gun delivered—and Cimarron's modern reproduction honors that proven design. This 20-inch barreled version pairs the classic exposed sidehammers and color case hardened receiver with practical features: it handles 3-inch shotshells, wears a wood stock, and comes in at a more maneuverable length than its 26-inch counterpart, making it ideal for ranch work, truck beds, or anyone who values the reliability of a simple, powerful scattergun.

The exposed hammers give you direct control and immediate feedback—there's no mystery about whether the gun is cocked and ready. The blued barrels and case colors evoke period authenticity without sacrificing function. A wood stock and schnabble forearm keep the gun balanced and pointable, qualities that matter when you're working livestock, dealing with varmints, or deploying the shotgun for home defense where the threat of scattered shot often speaks louder than precision marksmanship.

Cimarron didn't just copy a profile; they sourced an original and reverse-engineered it. The result is a gun that feels at home in a truck rack, on a saddle, or stacked in a safe. If you're drawn to side-by-side shotguns for their simplicity, reliability, and no-frills stopping power, the 1878 Coach Gun is a legitimate alternative to the usual pump and semi-auto suspects—and it carries genuine mechanical charm.

Frequently Asked Questions

What shotshell sizes does the Cimarron 1878 Coach Gun handle?

The CG1878-20 is built to safely fire 3-inch shotshells in both barrels.
