Modern shooters and collectors who value versatility, classic lines, and reliable single-action performance are increasingly turning to multi-caliber solutions that blend tradition with practical adaptability. Whether preparing for range duty, collecting a timeless piece, or adding a compact backup for trail use, a revolver that accepts multiple calibers can simplify logistics without sacrificing accuracy or feel.

PIETTA KING TRIO is a finely engineered 1873-style single-action revolver that delivers that versatility. The King Trio features three interchangeable cylinders to allow 9mm, .357 Magnum, .38 Special, and .38 Super options from the same platform. Built around a robust six-shot cylinder and a 5.5″ barrel, it combines a classic walnut grip, a case-hardened frame, and brass backstrap and trigger guard for both durability and period-correct aesthetics.

The King Trio’s configuration is valuable to shooters who want one platform that answers multiple roles. The ability to run 9mm offers economical practice and common defensive loading; .357 Magnum provides higher energy for hunting or defensive scenarios; .38 Special gives soft-shooting target and plinking options; and .38 Super adds high-velocity performance where available. At a street price of $729.99, it represents a compelling value for a caliber-flexible single-action revolver. Shop this product

Design and Handling

F.LLI Pietta’s workmanship is evident in the King Trio’s metal-to-wood fit and case-hardened finish. The 5.5″ barrel provides a balance between sight radius for precision and a practical length for field or range carry. The brass backstrap and trigger guard add period style while remaining robust under modern use. The walnut grip offers a comfortable hand fill for controlled single-action trigger breaks and follow-up accuracy.

Caliber Selection and Tactical Applications

9mm and .38 Super

9mm and .38 Super are practical for high-capacity load availability and lower recoil practice. Shooters can train economically with 9mm before stepping up to magnum loads.

.357 Magnum and .38 Special

.357 Magnum delivers proven stopping power and is a long-standing choice for defense and small-game hunting. .38 Special rounds provide soft shooting for precision drills and extended range sessions.

Pietta’s heritage in reproducing classic designs makes the King Trio notable for collectors who want historical styling with modern multi-caliber capability. The single-action platform preserves authentic operation while the interchangeable cylinders make it a functional tool for today’s shooter. View product details
