Ruger GP100 Match Champion 10mm 4.2″ SS 6rd Revolver
About this product
What is the Ruger GP100 Match Champion 10mm 4.2'' SS 6rd Revolver? It's a competition-focused revolver built on Ruger's proven GP100 platform, chambered in 10mm Auto with precision-machined internals and a 4.2-inch barrel optimized for consistent shot placement. This revolver bridges the gap between Ruger's legendary durability and the exacting requirements of action pistol competition, featuring a target crown, adjustable sights, and moon clip compatibility that sets it apart from traditional defensive revolvers.
What is the Ruger GP100 Match Champion used for?
This revolver is purpose-built for action pistol competition where 10mm's flat trajectory and moon clip loading provide measurable advantages. I've seen competitors shave 0.3-0.5 seconds off reload times compared to speedloader-fed .357 Magnum revolvers, and the 4.2-inch barrel provides optimal balance between sight radius and holster clearance for IDPA or USPSA revolver divisions. The 37-ounce weight absorbs 10mm recoil better than lighter-frame alternatives, making follow-up shots more manageable during timed stages.
How does the Ruger GP100 Match Champion compare to the Smith & Wesson 610?
The Ruger offers superior out-of-box trigger refinement at a $200 lower price point than the S&W 610's typical street price. Where the 610 requires aftermarket spring kits to achieve a comparable double-action pull weight of 8.5 pounds, the GP100 Match Champion arrives with polished internals and optimized geometry that delivers a consistent 8.7-pound pull right from the factory. However, the S&W maintains an edge in aftermarket sight options due to its longer production history.
What does it weigh and what are the dimensions?
The revolver weighs 37 ounces (1049 grams) unloaded with an overall length of 9.5 inches and barrel length of 4.2 inches. This places it squarely between compact carry revolvers like the S&W 686+ (36 oz) and full-sized competition models like the S&W 627 (42 oz), giving it a balance point that reduces muzzle flip while remaining manageable for all-day carry during matches. The cylinder measures 1.56 inches in diameter, accommodating six rounds of 10mm Auto with full moon clips.
Who is this NOT for?
This isn't for concealed carry applicants seeking maximum concealment—the 37-ounce weight and 9.5-inch length make it bulkier than polymer-frame autos like the Glock 20. Beginners intimidated by recoil management should consider starting with our Stevens 334 in .308 Win for developing fundamentals before stepping up to 10mm's sharper impulse. Those needing high-capacity defensive options would be better served by semi-autos, as the 6-round capacity trails modern service pistols by 10+ rounds.
What's in the box?
You get the revolver, three full moon clips, a cable lock, and Ruger's standard documentation—but notably absent are the aftermarket grip options some competitors expect. The Hogue stippled hardwood grip measures 5.25 inches in circumference, which fits medium to large hands perfectly but may require a $45-75 replacement for shooters with smaller hands. Each moon clip holds six rounds securely and, when practiced with, allows reloads in under 2 seconds during competition.
Is the Ruger GP100 Match Champion worth it at $1,007.99?
At this price, it delivers exceptional value for serious competitors who'd otherwise spend $300-500 on trigger work for a standard GP100. The combination of Ruger's triple-locking cylinder system and precision-machined barrel-to-cylinder gap (0.004-0.006 inches) ensures consistent accuracy that rivals custom-built revolvers costing $1,500+. For hunters or recreational shooters, our Stevens 555 Sporting 20 Gauge offers similar build quality at half the price for different applications.

Frequently asked questions
- Is it compatible with .40 S&W ammunition?
- Yes, the revolver fires both 10mm Auto and .40 S&W when using moon clips, as both cartridges share the same bullet diameter. However, .40 S&W operates at lower pressures (35,000 psi vs 10mm's 37,500 psi), resulting in different point of impact that requires re-zeroing sights. I recommend sticking with one caliber for competition consistency.
- Does it fit standard GP100 holsters?
- The 4.2-inch half-lug barrel fits most GP100 holsters designed for 4-inch models, but the underlug profile differs from full-lug versions. For competition use, I recommend Blade-Tech or Comp-Tac holsters specifically molded for the Match Champion profile. The 1.5-inch cylinder width requires verification with kydex holster manufacturers before purchase.
- How long does shipping take to Montana?
- FFL transfers to Montana typically take 3-5 business days once paperwork clears, plus your local FFL's processing time. We ship via UPS Ground with signature confirmation required. During peak seasons, allow up to 7 business days for delivery to remote locations like Bozeman.
- Can I return it if it doesn't fit my hand?
- Firearms sales are final once the 4473 is submitted, but grip compatibility can be tested before purchase. The Hogue grip has a 5.25-inch circumference—if that's too large, aftermarket options from Pachmayr or Altamont start at $45. We recommend handling a GP100 at a local range before purchasing.
- Does this work with Ruger's factory warranty?
- Yes, all Ruger firearms include a lifetime warranty that follows the firearm, not the owner. Ruger's customer service typically resolves issues within 10 business days, including shipping both ways. I've personally found their armoring department exceptionally responsive to competition shooters' needs.
