The Ruger GP100 in .357 Magnum is a tank of a revolver. This was built in the late 1980s as a successor to the Security Six, which was also a great revolver. The GP100 is incredibly beefy, having more metal built into the frame and the cylinder. Ruger states that the GP100 is capable of firing an unlimited number of full power .357 Magnum rounds without needing to cool down.
In contrast, numerous other .357 Magnum revolvers on the market need to cool down after firing enough rounds, or else the cylinder and action can lock up. The GP100 is available in both 6 round and 7 round configurations, in blued or stainless steel, and in a number of different barrel lengths. If you’re looking for a revolver that can take a lot of abuse and continue to run, the GP100 is a great option.
