I hesitate to mention buffalo bore 380. But I haven't shot a LOT of it and none in the p3 ... I have shot it in other guns and have tried their other calibers. Its expensive and I wouldn't shoot the stuff in volumes that damage the gun because of price, but if money were no object I still wouldn't use it all the time for fear (unfounded maybe) of wear and tear.
For most guns, if you put a 15-25% stouter recoil spring, you can run hot without too much damage. Still a little harder on it, but most of the damage from pounding is the slide being thrown too hard. I still don't recommend this approach, but if you go there, consider the spring.
