What are the key features of the Ruger GP100 Match Champion Stainless 10mm 4.2?

  • Chambered in 10mm Auto: This revolver handles a powerful cartridge, suitable for defense or hunting. The 10mm offers good energy transfer and a flat trajectory.
  • Stainless Steel Construction: The frame and barrel are made from stainless steel, providing corrosion resistance and durability. This material choice helps with longevity, especially in varied environments.
  • 4.2-inch Barrel: This barrel length balances velocity and maneuverability. It’s long enough to extract good performance from the 10mm round but still manageable for holster carry or quick handling.
  • 6-Round Capacity: A standard capacity for a revolver of this size, offering enough rounds for most self-defense scenarios or competition stages.
  • Polished and Optimized Action: Ruger has put work into the trigger pull, making it smoother for both single and double-action shooting. This helps with accuracy and shot placement.
  • Adjustable Rear Sight and Fiber Optic Front Sight: The sights are designed for precision. The adjustable rear sight allows for windage and elevation changes, while the fiber optic front sight is quick to pick up in various lighting conditions.
  • Hogue Stippled G10 Grip: This grip material and texture provide a secure hold, even with sweaty hands or during rapid firing. It helps manage the recoil of the 10mm cartridge.
  • Recessed Ledge on the Cylinder: This design feature allows for moon clips, which can speed up reloads, especially in competition settings.

Who should consider the Ruger GP100 Match Champion Stainless 10mm 4.2?

This revolver is built for specific users who appreciate its attributes.

Buy it if:

  • You’re looking for a robust revolver chambered in 10mm for self-defense or as a sidearm when hunting medium game.
  • You participate in revolver-specific shooting competitions and need a reliable, accurate platform.
  • You appreciate the durability and corrosion resistance of an all-stainless steel firearm.
  • You value a factory-tuned trigger and good quality sights right out of the box.
  • You want a revolver that can handle powerful loads consistently.

Skip it if:

  • You’re new to shooting and prefer a lighter recoiling cartridge; 10mm can be stout for beginners. Consider a .38 Special or .357 Magnum revolver for a softer introduction.
  • You need a higher capacity firearm for duty or extended engagements. A semi-automatic pistol might be a better fit for that requirement.
  • You are on a very tight budget and are looking for the absolute cheapest entry into a 10mm firearm. While reasonably priced for its features, there are less expensive options in other calibers.
  • You prefer a concealed carry revolver; its size and weight might be a bit much for everyday deep concealment. Look at smaller frame revolvers for easier carry.

What are the pros and cons of the Ruger GP100 Match Champion?

Like any firearm, the Ruger GP100 Match Champion has its strengths and weaknesses.

Pros:

  • Built to Last: The stainless steel construction means this revolver can take a beating and keep running. It’s a workhorse.
  • Powerful Cartridge: The 10mm Auto is a versatile and potent round, suitable for a variety of applications from defense to hunting.
  • Good Accuracy: The 4.2-inch barrel, tuned action, and quality sights contribute to good accuracy potential right out of the box.
  • Recoil Management: The weight of the steel frame and the comfortable Hogue G10 grip help in managing the 10mm’s recoil.
  • Reliability: Revolvers are generally known for their reliability, and the GP100 platform is no exception. It tends to go bang when you pull the trigger.

Cons:

  • Weight: At around 40 ounces unloaded, it’s a heavy revolver. This helps with recoil but can be a factor for all-day carry or if you prefer lighter firearms.
  • Capacity: Six rounds is standard for a revolver, but it’s less than many modern semi-automatic pistols chambered in 10mm. If capacity is a primary concern, consider a semi-auto 10mm.
  • Cost of Ammunition: 10mm ammunition can be more expensive and sometimes harder to find than more common calibers like 9mm or .45 ACP.

Frequently Asked Questions about the Ruger GP100 Match Champion 10mm

What kind of ammunition does the Ruger GP100 Match Champion use?

The Ruger GP100 Match Champion is chambered for 10mm Auto ammunition. It can also use .40 S&W ammunition when utilizing moon clips, though this is generally not recommended for best accuracy or extraction without moon clips.

Is the Ruger GP100 Match Champion suitable for concealed carry?

While it is technically possible to conceal any firearm, the Ruger GP100 Match Champion, with its 4.2-inch barrel and substantial weight, is generally considered too large and heavy for comfortable everyday concealed carry for most individuals. Smaller, lighter revolvers or compact semi-automatic pistols are typically better suited for that purpose.

Can I use moon clips with the Ruger GP100 Match Champion?

Yes, the Ruger GP100 Match Champion in 10mm is designed with a recessed ledge on the cylinder to accommodate moon clips. This feature allows for faster reloads, which is particularly beneficial in competitive shooting.

What is the main difference between the Match Champion and a standard GP100?

The Match Champion series features several enhancements over a standard GP100, including a polished and optimized trigger action, a half-lug barrel for reduced weight, specific sights (often fiber optic front and adjustable rear), and sometimes unique grip materials. These features are intended to improve accuracy and handling for competition or precision shooting.

Where can I buy revolvers online?

You can buy revolvers online, including the Ruger GP100 Match Champion, right here at Kansas Gunshop (kansas-gunshop.com). We ship firearms to your local FFL dealer for transfer, following all federal and state laws.

What kind of maintenance does a stainless steel revolver require?

Stainless steel revolvers still require regular cleaning and lubrication, especially after firing. While stainless steel is resistant to rust, it is not entirely rust-proof. Pay attention to the bore, cylinder chambers, and action parts. A light coat of gun oil on exterior surfaces can also help protect against environmental factors.

Is the 10mm Auto cartridge too powerful for a revolver?

No, the 10mm Auto cartridge is well within the capabilities of a robust revolver like the Ruger GP100. The GP100 platform is known for its strength and has been chambered in powerful cartridges like .357 Magnum for decades. The 10mm offers good performance in this platform.
