Ok, probably a bit more than you wanted, but here you go:
From the Manual, page 19: http://www.taurususa.com/pdf/pt-247-oss.pdf
3.1 - Use only high quality, original, factory-manufactured ammunition.
Do not use cartridges that are dirty, wet, corroded, bent or damaged. Do
not oil cartridges. Lubricant or other foreign matter on cartridges can
cause potentially dangerous ammunition malfunctions. Use only
ammunition of the caliber for which your firearm is chambered. The
proper caliber is permanently engraved on your firearm; never attempt to
use ammunition of any other caliber.
3.2 - The use of reloaded (remanufactured) hand-loaded, or other nonstandard
ammunition voids all warranties. Improperly loaded ammunition
can be extremely dangerous. Severe damage to the firearm and serious
injury to the shooter or to others may result. Always use ammunition that
complies with the industry performance standards established by the
Sporting Arms and Ammunition Manufacturers Institute, Inc., of the
United States, (SAAMI) or the equivalent from other countries.
.45 acp +p is a legit SAAMI spec:
Most ammunition manufacturers also market what are termed "+P" (pronounced "plus P") loadings in pistol ammunition, including the .45 ACP. This means the cartridge is loaded to a higher maximum pressure level than the original SAAMI cartridge standard, generating higher velocity and more muzzle energy. In the case of the .45 ACP, the standard cartridge pressure is 21,000 PSI and the SAAMI .45 ACP +P standard is 23,000 PSI. This is a common practice for updating older cartridges to match the better quality of materials and workmanship in modern firearms.
So you're good to go.
And yes, +P ammo, while not in any way hazardous, will accelerate wear & tear as noted previously.
