The GP100 platform is built on a robust, one-piece stainless steel frame with no sideplate and a triple-locking cylinder for secure alignment. This example carries a six-shot, six-flute stainless cylinder and a smooth double-action/single-action trigger system paired with a spurred, checkered hammer.

Chambered in .357 Magnum, the cylinder also accepts .38 Special, including +P, adding flexibility for ammunition selection. The grip-frame design accepts interchangeable grips and is currently fitted with a black rubber monogrip featuring inset hardwood panels.
