The Muscle Brake or the Painkiller would probably be your best bet. I've been very impressed with the Muscle Brake. I have one on a rifle and one on a SP. The rifle is a 375 BME shooting the 350gr Sierra Mk at 3000fps. It feels like a 308/30-06. The SP is a Savage Striker in 338/375 Ruger (often called the 338 Campfire). It's hard to come up with a comparable pistol to compare recoil to, but it's very manageable shooting 250gr Sierra Mks at 2650.

I don't have any first hand experience with the Painkiller Brake, but I imagine it's just as effective as the Muscle Brake while offering the same advantages as the other side discharge brakes.
With any of the side discharge brakes, you will most likely need to have a smith "time" the brake to the rifle so that the ports are properly positioned.
