Key Features

• Half-lug, slab-sided barrel — Why it matters: Reduces muzzle flip and speeds up follow-up shots during competition or range practice.
• Triple-locking cylinder — Why it matters: Locks the cylinder at the front, rear, and crane for consistent alignment shot after shot.
• Fiber-optic front sight & Novak LoMount rear — Why it matters: Gives you a bright, high-contrast sight picture in any lighting, no batteries needed.
• Transfer bar safety — Why it matters: Prevents accidental discharge if the hammer is struck, making it safe for daily carry and storage.
• Hogue Tamer Monogrip — Why it matters: Soaks up .357 Magnum recoil and fills the hand for a natural, repeatable grip.

Who It’s For

This revolver is built for shooters who want a production-grade match gun without a custom build. It’s ideal for USPSA revolver division, steel challenge, and range practice. It also works for anyone who wants a .357 that shoots flat and points naturally.

Pros & Cons

• Pros: Factory-tuned trigger, bright fiber-optic sight, half-lug barrel reduces weight, triple-locking cylinder for accuracy, satin finish hides holster wear.
• Cons: Fixed Novak rear sight limits elevation adjustment — you may need a different front sight height for some loads.

FAQ

Is the Ruger GP100 Match Champion suitable for concealed carry?

At 38 oz and a 4.2-inch barrel, it’s on the heavier side for everyday carry, but many shooters carry it in a quality OWB holster. It’s more practical for range, competition, or open carry.

What is the trigger pull weight on the Match Champion?

Per Ruger specs, the double-action trigger pull is approximately 9 pounds, and the single-action is around 3.5 pounds. The factory hammer and trigger are polished for a smoother pull compared to standard GP100 models.

Can I use .38 Special +P in this revolver?

Yes. The GP100 Match Champion is rated for .357 Magnum and .38 Special +P. The .38 +P loads will have less recoil and lower muzzle blast, making them great for practice or defensive use.

Does the Match Champion have interchangeable front sights?

Yes. The fiber-optic front sight is held in place by a roll pin. You can swap it for a different height or a tritium front sight if you prefer. The rear Novak LoMount is fixed but can be drifted for windage.

Is the Ruger GP100 Match Champion legal in all 50 states?

Yes. It is a standard revolver with no restricted features. It ships to all 50 states with no magazine capacity issues.
