I have the Burris 2x-7x-32mm scope on my .454 Casull. I have shot about 100 rounds through it, and the scope has been perfect. Optics are clear and adjustments are precise. My only complaint, which really isn't that big, is that the eye relief changes quite a bit when you start increasing the power. As such, from the way that it is mounted, I really can't get it past about 4x anyway because the it starts to "black out."
Now, the Elite 3200 handgun scope, on the other hand, is just as good as the Burris, AND (like GB said) it has 20" of CONSTANT EYE RELIEF! I don't personally own an Elite 3200, but I have shot a 480 ruger with one and it's tracking was great, just like the Burris.
I think that the Burris 3x-12x is just way too much power, especially since the eye relief will shrink soo much.
Like Jon said, your best bet is the Elite 3200.
