The odds are 99% that most blackies will vacate the territory if they know you are there and stirring. (Trained garbage bears being something of an exception.) Pepper spray will probably work better at repelling a bear than a handgun. That said...
Black bear are about the size of humans - 150 to 250#s. Unlike humans they are not thin skinned and for a given weight their muscle structure is much thicker than a human's and the bone is heavier.
I'd second the recommendations for as heavy a bullet going as fast as you can tweak it.
To stop a seriously annoyed blackie you will need a CNS hit, or to break bone, such as the shoulder. Given a bear's bone structure a heavy 9mm at close range "might" break a shoulder joint. The smaller, leaner the bear the better the odds. But I wouldn't want to bet on it regularly. Especially since you don't get to pick the bear - and probably won't get to pick the shot.
For a CNS hit you're talking about the brain or spine. For that a heavy 9mm slug should work if you're shooting from a point above the bear - I don't think you could reliably expect to clip the spine with a side shot through the shoulders.
The drawback is that you and the bear both are apt to be in a great hurry and the brain pan and spinal cord are not large targets.
If the bear is "on" you before you see it (i.e., pulling you out of the tent/sleeping bag or you stopped to clean fish somewhere between a sow and her cubs)your best bet is to curl up and play dead. I'd note that in recent decades there have been instances of black bear looking at humans as a food source - in which case playing dead is probably not the right choice. If you can get to a gun in this situation your best option is to try to poke the barrel in the bear's mouth and go for the gold.
Alternatively, put as many as you can somewhere in the body cavity and hope the bear bleeds out or becomes discouraged while you're still in good enough shape to benefit from skilled medical attention.
In this scenario an auto is of questionable advantage. True - it has a much higher ammo capacity - but keeping enough space for the slide to operate effectively is iffy.
The odds are real high that you'll never have to find out how effective a P-35 is against an attacking black bear. In fact the odds are probably about the same as for you winning the state lottery. I wish you luck in both endevors.
