The Pietta GWII Buntline is a single-action revolver chambered in .45 Colt with a 12-inch barrel. It is built on the 1873 platform, the same general pattern as the Colt Single Action Army, and finished in blued steel with case hardened components. The Buntline name refers specifically to the extended barrel length, which has a long history in American frontier lore.

Detailed Features 

 
The 12-inch barrel is the defining characteristic. It adds sight radius over a standard 4.75" or 7.5" barrel, which can improve accuracy for deliberate target work. The .45 Colt cartridge has been around since 1872 and remains popular in cowboy action shooting for its mild recoil in standard loadings. Fixed sights keep things simple and historically correct. 
 
The blued and case hardened finish is visually appealing and appropriate for the period-correct aesthetic. Pietta has a long-standing reputation for quality production revolvers at accessible price points. 
 

Usage Scenarios 

• Cowboy action shooting (CAS/SASS) where the 1873 platform is one of the standard action types. 
• Collector use and display, given the historical significance of the Buntline configuration. 
• Recreational range shooting for anyone who enjoys single-action revolvers.

The Pietta 1873 Buntline in .45 Colt tends to attract two types of buyers: cowboy action shooters and collectors drawn to its historical associations with the Old West. Both groups generally come away satisfied.

Craftsmanship feedback on Pietta revolvers is typically solid: smooth action, good fit between components, and the blued finish drawing consistent compliments. The 12-inch barrel is frequently mentioned as a visual and functional highlight, adding sight radius for deliberate target shooting.

The practical critiques are predictable and known going in: the long barrel is awkward for anything requiring quick handling, and loading/unloading through the gate on a traditional single-action design takes time and attention. A few users report occasional timing or misfire issues, though these appear to be outliers rather than a systemic problem. Most who buy it for CAS competition or as a collection piece report satisfaction.
