They had a much tighter than average cylinder to forcing cone fit, and thus yielded more energy through the barrel rather than out the sides. The barrel shrouds also locked the barrels in front and back, so barrel flex was kept at a minimum, which was generally the explanation for their better-than-most accuracy. I considered them among the finest revolvers available at the time, but rather out of reach for me in price. To me, they are still desireable, and I wouldn't turn one down if it presented itself to me at the right price, and I'm not even a revolver guy.

I am the weapon; my gun is a tool. It's regrettable that with some people those descriptors are reversed.
