A friend has one of these - the 12" S&W Performance Center version (the one pictured with the sling), and I've shot it off a pistol rest.
The 325 gr bullets are considered "light" loads and have severe recoil. The 440 gr full-house loads have recoil beyond severe, and will bruise the hand (and possibly forehead) of even experienced shooters. The article says the recoil is manageable. Yes, it is, for someone used to shooting .454 Casull. For someone used to a 9mm or even a .45 ACP, it's not going to be fun.
Recall that this is a revolver, so there is no gas-operation mechanism to lessen any recoil like in the .50 Action-Express Desert Eagle -- it all comes back to your hand and arm.
Accuracy is very good. Assuming you don't flinch, the muzzle velocity is such that bullet drop is non-existant at ranges under 50 yards, so you'll almost certainly hit what you were aiming at.
