  The barrel has an 11-degree target crown and the internal components are polished for a smooth double-action pull. The trigger centering boss and hammer centering shims reduce side play, which tightens consistency across the trigger stroke. The adjustable rear sight allows precise zeroing for specific loads or distances. The GP100 also accepts .38 Special ammunition, which adds flexibility for lighter practice loads.

Competitive shooters and revolver enthusiasts are generally positive about the GP100 Match Champion. The smooth double-action trigger pull is the feature most consistently praised, with many noting it requires little to no modification for competition use. Adjustable sights are a practical advantage for those shooting at set distances.

Build quality consistently gets high marks. The stainless frame is durable and the Hogue hardwood grips handle the .357 Mag recoil without becoming uncomfortable. The ability to run .38 Special rounds is valued for practice sessions where recoil and cost matter. Weight at 38 oz is occasionally flagged by those who want a lighter carry option; this is better suited for range use and competition than daily carry. Pricing is generally seen as competitive for the quality delivered.
