Is the P09 different from the P07 - except for size? I ask because I have a P07 and plan to get a P09 later this summer.
So far (two cleaning/lubings) gets the same thing my other handguns get - Mobil 1. A drop on each spring, each pin I can see, the place where the sear/hammer meet, the firing pin safety block, two drops (one at the front and one at the back on each rail), one on the barrel lug where it contacts the slide stop, one or two on the barrel near the front and anything that looks dry inside.
I don't mind lube getting on my hands/shirt. I don't live in a dry dusty climate so there's nothing but pollen around here (lots of that) to collect in the oil.
The only thing I've ever "greased" are my M1 Garands and M1A. I just use oil on the handguns and shotguns. Oh, wait one, the SIG 556R gets grease on the rails because the receiver/area stays so clean vs. the AR15's the grease is good for multiple range trips (the receiver doesn't get dirty inside so the grease doesn't mix with burnt powder/residue and need to be removed every time).
