Gort,
The Taurus Firearms sight does not have the User's Manual for these available yet. Indeed, they are not available in any stores here in the Twin Cities area of MN. I wanted to handle one, but now see that they are fairly heavy and long barreled. It almost appears that Taurus has made the Thunderbolt for the Cowboy Action shooting crowd. A visit to the Taurus internet page seems to bear this out. Fairly long, heavy rifles for a pistol cartridge hunting rifle in my opinion.
