For hunting, I would carry it in a chest rig. That way I wouldn't have the weight dragging my trousers down, and could have reasonable access to it. That pistol isn't designed for fast draw in any case. Plus, a nice chest rig with a flap over the butt of the pistol could help protect the pistol from the rigors of going through the bush. But I'm lucky and can make my own holsters. There are plenty of decent leather workers out there that could make you a decent rig.
edited to add: I would support the pistol with straps over both shoulders, a strap around the back and anchoring the pistol down with straps going around your trouser belt on both sides. That would keep the pistol in one place, and make it very comfortable to wear, while providing easy access to it. I don't suppose extra magazines would be needed, but perhaps a few extra rounds on one of the straps would be useful.
