The Ruger GP100 Match Champion is a 10mm DA/SA revolver with a 4.2-inch barrel, satin stainless finish, Hogue stippled hardwood grips, and a fiber optic front sight with adjustable rear. It's built on the GP100 frame, one of the more overbuilt revolver platforms on the market, which helps manage the recoil of a full-pressure 10mm load.

Features 

The transfer bar safety prevents discharge unless the trigger is fully depressed. Moon clips are included for loading. They allow faster reloads than individual rounds through the ejector. The DA trigger pull is heavier, as expected on the GP100; single-action pull is notably lighter and well-suited for precision work. The adjustable rear sight can be dialed for windage and elevation.

Owners of the GP100 Match Champion in 10mm tend to be positive overall, with a few recurring discussion points.

Build quality is the most consistent praise. The stainless GP100 frame is thick and well-fitted, and users frequently note it handles 10mm recoil without drama. The satin finish is well-received aesthetically, cleaner-looking than matte without being flashy.

The trigger gets attention in both directions. DA pull is on the heavier side, which is typical for the GP100 and not a surprise to anyone who's shot one before. SA pull is clean and earns good marks for precision shooting. Some buyers swap the spring set for a lighter DA pull.

The fiber optic front sight and adjustable rear are practically useful additions for a revolver intended for range and competition use.

Recoil with 10mm is more pronounced than with .357 or .38, and opinions differ on how well it's managed. Shooters already familiar with large-bore revolvers handle it fine; those new to 10mm take more time.

Moon clips come included, and users find them helpful for competitive or range use where reload speed matters.

Price sits at the higher end for revolvers in this category. Most buyers consider it fair given the quality, but comparisons to S&W alternatives are common.

The trigger is noticeably better than the standard factory Ruger triggers I have used. Shooting .40 S&W is especially pleasant, while 10mm gives me the extra power when wanted. Switching between them does mean adjusting the sights for distance, and moon clips disappear quickly during an enjoyable session.
