I want to prove in my P99 9mm, the defensive ammunition +P, but I am not sure that the P99 is made to resist this type of the ammunition. I will appreciate its experience and advice on this subject.

Short answer is:

Yes you can shoot +P and +P+ ammo in your P99. However it has the side effect of increasing wear and tear on the pistol due to increased pressures and forces exerted on it.

I was told by people on this board with experience with +P ammo that constant use will accelerate wear and tear on the pistol.  But shooting 200 rounds to test functionality and then using it as a carry round with occasional firings of it to keep practice on it won't do much if any harm to the weapon.  This idea makes good sense to me.

I just have to find a cheap source for good +P ammo
 From test data from a few places, Cor-Bon 90 and 115 gr seems to be very good at transferring energy w/o overpenetration.  I'd like to get some if I could find it for a reasonable price.  

Currently I carry 9mm 115gr Winchester JHP - its the whitebox stuff.  Not the best stuff out there I know.

Bottom line; unless you shoot nothing but +P ammo and shoot it a lot, I feel that it won't have an adverse effect on your weapon. It would be similar to encountering the occasional hot load in a set of standard pressure rounds - you won't even notice it.
