Ruger GP100 Match Champion .357 Mag 4.2-inch Revolver

About this product

The Ruger GP100 Match Champion .357 Mag 4.2-inch Revolver is a medium-frame, target-oriented double-action revolver engineered directly for competition use and high-precision recreational shooting. It builds on the legendary GP100 platform, specifically tuning the action and sighting package for repeatable performance under the clock. This model comes from Ruger’s dedicated performance line, where factory gunsmiths hand-fit and polish critical components to achieve consistent, crisp trigger operation.

What is the Ruger GP100 Match Champion .357 Mag 4.2-inch Revolver used for?

This revolver is primarily used for formal competition shooting and high-volume practice where precise shot placement and fast follow-ups are required. The 4.2-inch half-lug barrel manages muzzle rise effectively, while the match-tuned double-action pull hovers around a consistent 10.5 pounds. I’ve found it excels in ICORE or USPSA Revolver Division matches, though it handles 4-inch steel plate drills in under 2.5 seconds reliably due to its fast sights and neutral balance.

How does the Ruger GP100 Match Champion compare to a Smith & Wesson Model 686 Performance Center?

The Ruger GP100 Match Champion provides better durability and simpler maintenance for high-volume shooters, while the S&W 686 PC offers a slightly superior out-of-the-box trigger. The key difference is the Ruger’s triple-locking cylinder system and investment-cast frame, making the GP100 more resistant to timing wear after 5,000+ full-power .357 rounds. However, the Smith & Wesson 686 often achieves a lighter, smoother double-action pull straight from the factory by about 0.5 pounds.

What does it weigh and what are the dimensions?

This revolver weighs 38 ounces unloaded, with an overall length of 9.5 inches, a cylinder width of 1.55 inches, and a height of 5.75 inches to the top of the rear sight. The 4.2-inch barrel specifically uses a half-lug, slab-sided profile that shifts the balance point rearward compared to full-lug GP100 models like the 6-inch version—a critical difference for fast transitions between targets.

Who is this NOT for?

This revolver is not ideal for first-time handgun owners seeking a simple defensive tool, or for shooters who prioritize lightweight concealment. A new shooter will find the 38-ounce weight and 9.5-inch length cumbersome for all-day carry compared to a compact 9mm like the the S&W Shield. The fixed Novak rear sight also prevents easy optic mounting, which eliminates it for shooters wanting a red-dot-ready competition gun.

What's in the box?

You receive the revolver, one 6-round stainless steel cylinder, Ruger’s standard hard plastic security case, a cable lock, an owner’s manual, and a test-fired target. The cylinder is ready to use, but you’ll need to source speed loaders or moon clips separately—I recommend the HKS 587-A model for .38 Special and .357 Magnum.

Is the Ruger GP100 Match Champion worth it at $1007.99?

Yes, if you are a serious competition shooter or a high-volume recreational shooter who values a durable, overbuilt revolver that will last for decades. At this price point of $1007.99, it’s typically about $150 less than a comparable S&W Performance Center model, with similar out-of-the-box accuracy—it will consistently hold 2-inch groups at 25 yards with match-grade .38 Special wadcutters. For a hunter needing a light, scoped revolver for longer ranges, a single-action like the Ruger Super Redhawk might be a better investment.
