The Colt Single Action Army (SAA) .45—better known as the "Peacemaker"—is arguably the most legendary handgun of the Wild West. Umarex has adapted this monument of firearms history into a CO2-powered air pistol, creating a collector's item that blends historical authenticity with modern recreational ballistics.

Here is a detailed report on the Umarex replica.


1. History of the Original

Before diving into the CO2 variant, let's look at its roots: The Colt SAA was introduced in 1873 as the standard service weapon for the U.S. Cavalry. It replaced outdated percussion revolvers and utilized the then-modern centerfire cartridge in .45 Colt caliber.

  • The Nickname: It earned the name "Peacemaker" for its role in bringing order to the often lawless American frontier.

  • The Mechanism: As the name "Single Action" implies, the hammer must be manually cocked before every shot. This rotates the cylinder and readies the firearm to fire.


2. The Umarex Adaptation: Engineering & Design

Umarex holds the official Colt license, meaning this replica not only looks like the original but also features the original logos and markings.

Build Quality and Feel

The gun is made almost entirely of full metal. Its weight of approximately 867g (1.9 lbs) is very close to the real revolver. A standout feature is the loading system: pellets or BBs are inserted into brass charging shells, which are then slid into the cylinder through the loading gate just like real cartridges.

Power Source

The 12g CO2 capsule is concealed within the grip. The Allen key required to pierce the capsule is cleverly integrated into the inside of the grip scale, eliminating the need for external tools.


3. Performance and Precision

The Umarex Colt SAA is available in two main versions: a smoothbore barrel (for 4.5 mm steel BBs) and a rifled barrel (for 4.5 mm pellets).

Feature Details
Caliber 4.5 mm (.177) BB or Pellet
Magazine Capacity 6 rounds (via shells)
Energy approx. 3.0 to 3.5 Joules
Velocity ($v_0$) approx. 115 - 120 m/s (380-400 fps)
Trigger Single Action Only
    • Precision: The pellet version with the rifled barrel is surprisingly accurate at distances up to 10 meters. The BB version is better suited for rapid "plinking" at cans.

    • Efficiency: One CO2 capsule typically lasts for 60 to 80 shots before the pressure noticeably drops.


    4. Intended Use

    The Umarex Colt SAA is not a traditional competition target pistol. Instead, it specializes in:

    1. Plinking: Shooting at cans, reactive targets, or bottles in a private setting.

    2. Cowboy Action Shooting (CAS): Many Western enthusiasts use this revolver for authentic-style drills and hobby competitions.

    3. Collectors & Display: Due to its high-quality finishes (nickel, blued, or "antique look"), it is a highlight in any collection.


    5. Conclusion

    The Umarex Colt SAA .45 is one of the finest replicas on the market. It impresses not through high-tech features, but through its nostalgic operating concept. The process of loading the shells, the characteristic "three clicks" of the hammer, and the heavy metal feel provide an extremely realistic experience.

    "Anyone looking for the flair of the Wild West without needing a firearm license cannot overlook this revolver."

    Pros:

    • Superb full-metal craftsmanship.

    • Authentic loading system with brass shells.

    • High collector value due to the Colt license.

    Cons:

    • The loading process is inherently slow (tedious for those who want high-volume fire).

    • No adjustable sights (fixed notch and blade).
