I think that too many people buy guns over silly things like balance. The P320 Compact is a good defensive/fighting pistol. I bought one myself as I wanted something around the Glock 19 size that didn't have finger grooves or grind my middle knuckle. It's bound to have a huge aftermarket due to the military contract and from all I've seen the guns are dead nuts reliable and well made. I like 1911s but I don't carry them. They sure do balance great, but they have a low capacity for their weight and are more complicated beasts to take care of. Gotta break many of them in, many aren't reliable out of the box, often shooters have to buy a few different types of mags and carry ammo to find a combo that works, etc... When picking a carry pistol, I really recommend looking for something that has (lemons aside) a reputation for just working out of the box. Getting used to the feel, balance, etc is a training and familiarity issue.
