Pietta 1873 Great Western II U.S. Marshal .45 LC/ACP 4.75in

The Pietta 1873 Great Western II U.S. Marshal .45 LC/ACP 4.75in is a single-action, six-shot revolver that brings authentic Old West styling and modern dual-caliber flexibility to your collection. Chambered for both .45 Long Colt and .45 ACP via the included extra cylinder, this 4.75-inch-barreled six-shooter pairs a case-hardened frame with a blued barrel and cylinder, topped with walnut-style grips bearing the U.S. Marshal engraving. It’s a working piece of history that shoots two of the most versatile revolver cartridges on the market.

Key Features

• Dual-Cylinder Combo — WHY IT MATTERS: You get two calibers in one revolver, letting you shoot affordable .45 ACP at the range or classic .45 Long Colt for cowboy action and hunting, all without a second gun.
• 4.75-Inch Barrel — WHY IT MATTERS: This is the iconic “Sheriff’s” barrel length, balancing concealability with a full sight radius for accurate shooting, and it’s the same length used by legendary lawmen of the 19th century.
• Case-Hardened Frame & Blued Finish — WHY IT MATTERS: The traditional color case-hardening on the frame resists wear and looks authentically period-correct, while the blued barrel and cylinder offer a deep, rich finish that holds up to holster use.
• U.S. Marshal Engraving on Grips — WHY IT MATTERS: The walnut-style grips feature a laser-engraved U.S. Marshal badge, giving this revolver a distinct collector-grade identity that stands out on any gun show table.
• Exposed-Hammer Single-Action — WHY IT MATTERS: You control the hammer manually for a crisp, light trigger pull every time, exactly as the 1873 design intended, making it a joy for target work and cowboy action shooting.

Who It’s For

This revolver is built for collectors who want a historically accurate piece with real shooting versatility. It’s also perfect for cowboy action shooters who need a backup gun that can handle both .45 Colt and .45 ACP without swapping platforms, and for gun show enthusiasts who appreciate a firearm that tells a story right out of the box.

Pros & Cons

• Pros: Dual-cylinder versatility is a huge plus for shooters who want to practice with cheap .45 ACP then load up .45 Long Colt for serious work. The 4.75-inch barrel is a sweet spot for holster carry and accuracy. The U.S. Marshal engraving adds real collector appeal.
• Cons: The single-action design requires manual cocking for each shot, so it’s slower than a double-action revolver in defensive scenarios. Also, the walnut-style grips are a bit slick for heavy recoil loads — you may want aftermarket checkered grips for extended range sessions.

FAQ

Can I shoot .45 ACP without moon clips in this revolver?

Yes — the included .45 ACP cylinder uses standard .45 ACP headspacing and does not require moon clips. Just load and shoot, though you may need to push the empties out with a rod, as the cylinder lacks an ejector star for rimless cases.

Is the extra cylinder pre-fit or does it need gunsmithing?

The extra .45 ACP cylinder is factory-fit to this specific revolver. Per Pietta specs, it should drop in and function without additional fitting. However, always check timing and cylinder gap with a feeler gauge before live fire.

What holster fits the 4.75-inch barrel?

Standard single-action holsters for 4.75-inch barrels (often called “Sheriff’s” or “4.75-inch” holsters) work perfectly. Brands like Triple K and Galco make leather options that fit the Great Western II profile.

Does this revolver have a transfer bar safety?

No — the Pietta 1873 Great Western II uses a traditional half-cock safety notch. You should carry with the hammer down on an empty chamber, as is standard for single-action revolvers of this design.
