Hello out there:

I just put a NIB P7M8 on layaway. When inspecting the pistol @ the shop, I noticed some whitish grease on the gas piston. The scraper and the brush are in the box. Where can I find this grease, and do I need it? What maintenance tips can anyone give me, beyond what the owner's manual says? Also, are adjustable night sights available? I especially like the yellow/green ones.

Additionally, I may be looking into getting this weapon hard chromed. I know Arizona Response Systems is one place...any other recommendations?

Finally, are there any DON'TS I should be aware of, other than avoiding detail stripping, and not using super hot +Ps?

Thanks!
