I have one and love it. Mine shoots one-inch groups at fifty yards with a 2x Leupold mounted on it. By the way, if you want to shoot a MUCH quieter load in it you can use the old .22 WRF cartridges, now loaded again by CCI and Winchester. They shoot a 45 grain hollowpoint bullet at about the same velocity as you would get from a .22 long rifle out of the pistol (mine shoots them at about 1000 fps). The are a little cheaper than the magnum shells and great for rabbits and squirrels. The have the same diameter bullet that the magnum bullets have and are very accurate (also shoot to the same point of aim in my revolver).
Just a note - the new .22 WRF boxes have a warning that states: 'not for use in revolvers' on it. When I contacted CCI about this, they told me the warning was meant for old cheap .22 WRF revolvers (not magnum revolvers), some of which have .22 long rifle diameter bores on them. They shoot great.
