So I got a P7 two months ago, gave it a good cleaning, and took it to the range (awesome). Now I'm doing more of a conditioning and further cleaning (not going into the clockwork though). I haven't worked with older steel of this quality before and wanted to post what I'm doing and ask some opinions to make sure I'm not doing anything detrimental.
First of all, I cleaned out the gas cylinder, bore, feed ramp, basic run through with M-Pro 7. It came with a light layer of grease on the rails. Grease didn't look dirty so I left it, though I might de-grease and CLP lube it later.
I started cleaning the magazines tonight, took them apart, M-Pro'd the insides, and then put a very fine layer of CMP Break Free on the springs with a rag. That's it, they were pretty dirty. I found tons of grease inside one of the mags when I took it apart, I don't know who thought that was a good idea. Cleaning all that out.
My main question is conditioning. When I'm doing a gun, I usually always run an oiled patch through the barrel after cleaning it and then use a rag to apply a light layer of CLP oil over every external and accessible internal surface just to have a layer to keep moisture out, paying extra attention to friction points. I'm not putting any lube whatsoever in gas cylinder. Good idea or bad idea with the P7??
I noticed these textures (the lines and pockmarks) on the slide, I don't know if they're something I need to worry about?? Sorry about picture size, I can't seem to get them smaller.
Any advice is appreciated, I can only afford one.
