The KGPF-330 designation identifies this as a stainless, 3-inch, fixed-sight GP100 with a half underlug, a configuration no longer in current production. This setup delivers a streamlined profile while retaining the durability associated with Ruger’s GP100 line.
It features an investment-cast stainless-steel, one-piece frame with Ruger’s triple-locking cylinder design for secure lockup. The six-shot, fluted cylinder uses a star extractor and is actuated by a left-side push-button cylinder release.
The double-action/single-action system includes a smooth-faced trigger, a spurred and checkered hammer, and Ruger’s transfer-bar safety. Sighting is straightforward with a pinned ramp front sight carrying a red/orange insert and a fixed topstrap groove rear integral to the frame.
Factory details include satin stainless finish on the frame and cylinder, compact one-piece black rubber grips with inset wood panels, and a pinned front sight. Markings include the Ruger phoenix rollmark, Southport, Conn. U.S.A. address, and the standard read manual warning.
