If I remember, my PT145 manual made some statement that ammo exceeding SAMMI specs will accelerate wear on the gun, then said something about being less safe to shoot. Boilerplate telling you not to overuse hotter ammo. I range shoot regular pressure ammo, like Wolf. Then after making sure it functions in the gun, I then carry something hotter. I like Double Taps (particularly the 185gr) because they are technically not +P, but give the higher velocities. I like the hot rounds in the .45 but don't want to tempt fate with alot of +P use. Even the Double Taps I don't plan to shoot except occasionally.
