Wow! Thanks. That was exactly what I was looking for.
I'm going to try that when I get home from work. I pushed out the pin that is at the front base of the grip because I was getting some sticking with the sear bar due to build-up of crud and I thought I could clean those parts better by "moderately" disassembling the squeeze cocking mechanism. The problem with that is that, on reassembly, the squeeze cocker spring seemed really strong - totally counterintuitive really - the way I was trying to reassemble it, and following the old "don't force anything" rule I thought I better consult a manual before I (1) break the gun, or (2) give up and take it to a gunsmith.
I'll post some pictures.

ghostie, you got bigger 'boys' than I do!
From the Ultimate Pro's and Con's on the same link:
14. Disassembly not for mere mortals. A "detail strip"
can involve a lot of head/heart ache. The gun has a fair number of parts but the real problem is the gun's unorthodox design [Expert reassembly tip, use grease to hold in the mag release spring--otherwise you will go mad trying to hold everything together while attempting to drive in the assembly pin]. An armorer at HK told me that they regularly have to reassemble guns for owners who let curiosity get the better of them. Fortunately, there is really no reason to strip it down beyond a "field strip." Just spray in some gun oil and wipe.
I just field strip and blast away with Gun Scrubber. I can't wait for the pics. Be careful and good luck!

Yah, it was a little daunting. The squeeze-cocker assembly isn't that bad though, at least once I had a manual to follow. I don't think I would want to mess around with disassembling the trigger though. The manual is talking about holding it together with your hand and then doing two things at the same time, etc. Sounds very tricky.
My problem was that I was trying to "lightly oil" the components of the squeeze-cocker assembly. Don't do that. What I ended up with was sticky parts caked in powder residue and oil... and yah, I was cleaning it after trip. The manual is recommending just wiping them with one of those cloths that lubricate things a bit, so I did that.
It is all working well now though. The P7 is definitely not a heavy (or even moderate) lube gun. It's not like a SIG. The GLOCK (barely anything.. basically just the rails) approach is the one to take with the P7. But with the P7 there aren't really much for rails... so I'm just putting a dab on the little "rails" at the back.
Any other cleaning maintenance ideas for the P7 would be appreciated. Some people are saying clean the piston really well. Others say not at all. I've been brushing out the channel for the piston, and keeping the piston itself relatively free of blackness, but not going to extremes.

The only thing I can recommend is not to put a brush or anything abrasive on the piston. I usually use a wet patch and wipe off as much as I can and leave it at that. The tube (channel) can be cleaned with a wet patch, followed by a few dry patches. If it really, really needs it a .270 bronze/brass brush will fit (I never had to use one on my P7M8 but I have the brush on hand). My lube routine is to put a few drops of Hoppe's Elite gun oil on a patch and wipe the rails and internals including the barrel and recoil spring and the frame leaving a very light coating. For the squeeze cocker area I use Remington Dri Lube--a very light spray of it. You're right in saying that this pistol doesn't have high lubrication needs. That's all I do with mine but I'm not an expert and I'm a newbie to the P7 family. 
A little off topic, ghostie, I'd really like to see a range report from you about your shooting and general impressions of the P7. I've enjoyed reading your previous reports.
