Most modern guns are rated for +P like someone else stated. +P is all I carry. It and +P+ are both expensive ammo, and I don't train with it for that reason. I run a few mags every once in a while to make sure I am used to the difference in feel and to cycle ammo batches. At that rate you won't create any significant extra wear on the gun or its components.
Your owners manual should cover what it can handle. If not, call the manufacturer. Easy, Peasy.
Most modern handguns can be used with +P, but certainly check your owners manual.
The real question is what purpose does it serve? If your choice of carry ammo penetrates and expands adequately in standard pressure format, all +p is going to give you is extra recoil, more wear and tear and a higher cost per round. If you practice with regular cheap target loads, there can be a considerable difference in how your gun handles.
Now, if you're carrying something with a very short barrel, to the point where standard velocity ammo won't expand reliably, then you can make a case for it.
