With the changeable front sight setup. Apparently that's rare for the 3-inch barrels. Saw this on Rugerforum.net.
There was one more of them an hour ago, so they're going fast. No, I didn't buy it. I can't convince myself that a gun as big and heavy as a GP100 really makes sense as a 3-incher. But I know y'all like yous some 3-inch revolvers.
