Hornady XTP Ammo in G29SF - 155, 180, or 200 Grain?

I'm planning to order some Hornady XTP ammunition - the actual Hornady brand, not ammo from other companies that use their XTP bullets. I'm picking Hornady because it is readily avaiable to me at a reasonable price for premium hollow-point ammo. I will use it in my Glock 29SF.

My quandry is which of the three available bullet weights to select. I know the XTP is noted for deep penetration and reliable (though not huge) expansion. That's okay with me. I mostly use my 29SF in the woods where bears and mountain lions are a concern. I'm guessing that the 200 Gr bullets would be best if I had to shoot a black bear. I also sometimes carry it where defense against humans is the only real concern. For that, I'd guess the 155 or 180 Gr. bullets would be best. I don't plan to hunt with it.

Given the relatively short (3.5") barrel of the gun, would I be better off going with the 180 grain bullets to get adequate velocity - even in the woods? Or is the heavier bullet always better for bear defense? Will the XTPs penetrate enough for this, or should I go with a 200 Gr. FMJ? Also, is there any real downside to picking the 180 or even 200 Gr XTPs for defense against humans? The reports I've read seem to indicate similar expansion for all of them.

Finally, I know this is not really "hot" ammunition, but is it considered full-power for a 10mm? Is one of the three bullet weights loaded hotter?

Thanks
