I always thought the P7 was near perfect as they came from the factory.
No mention in the list of work of a check on the gas piston wear - that should be mandatory.
I would beware of any dimensional modifications to parts like the sear lever, firing pin "wing" or drop safety to "improve" trigger pull as the system is already finely balanced for proper function of various interactive parts.
Feed reliability upgrade on a P7 would be like upgrading horsepower on a ZR1.
