Ruger GP100 10mm

About the Ruger GP100 10mm

The Ruger GP100 10mm is a six-shot double-action revolver chambered in 10mm Auto, produced by Sturm, Ruger & Co. as a TALO distributor exclusive. Because the 10mm Auto is a rimless semi-automatic cartridge, the revolver headspaces and extracts its rounds using full-moon clips, which also speed up loading and unloading. Built on the rugged GP100 platform, it uses a solid stainless-steel frame, the signature triple-locking cylinder, and a transfer-bar safety that make it well suited to the higher pressures of full-power 10mm loads. The 3-inch model (Model 1780) pairs a full-length ejector shroud with a fiber-optic front sight and a Novak LoMount adjustable rear sight, blending defensive carry practicality with the accuracy expected of the GP100 line.

Introduced to satisfy demand for a revolver that could shoot the potent 10mm Auto cartridge favored by handgun hunters and outdoorsmen, the GP100 10mm leverages moon-clip technology to tame a rimless semi-automatic round in a wheelgun. The result is a heavy-duty stainless revolver that delivers near-.41 Magnum performance while feeding from inexpensive, widely available 10mm ammunition.

Ruger GP100 10mm specifications

The GP100 in 10mm Auto requires moon clips to fire, as the rimless cartridge cannot headspace on a conventional revolver's recessed chamber mouth. Offered chiefly as TALO distributor exclusives, including a 3-inch Model 1780 with fiber-optic/Novak sights and a longer Match Champion configuration. The double-action trigger pull is approximately 12 pounds (53 N) with a single-action pull near 5 pounds (22 N).
