    The 4.2-inch barrel has an 11-degree target crown for consistent bullet release. The polished internal components, trigger centering boss, and hammer centering shims combine to produce a smooth double-action pull with a sharp let-off. The GP100 accepts both .357 Magnum and .38 Special ammunition.

The GP100 Match Champion draws steady positive feedback in revolver circles. The smooth trigger pull and adjustable sights are the most commonly praised features, and many shooters report the trigger works well for competition without modification.

Build quality is highly regarded: the stainless frame feels solid and the Hogue grips absorb .357 Mag recoil well enough for extended shooting sessions. The lighter .38 Special loads are a practical option for practice. Weight is the main practical trade-off, with 38 oz making this better suited for range and competition use than carry. Price-to-quality comparisons generally favor the GP100 Match Champion, though a minority of buyers feel competing revolvers offer better value.
