I disassembled my new P-01 this afternoon to give it a good cleaning, but mostly out of curiosity and to get familiarized with it. What a breeze it was. My questions to you are: Do you use a specialized gun grease for the rails or will just regular gun oil do (I use Hoppes Elite)? Also, have you had any problems with the grip screw-heads stripping? I took the grips off to clean the gunk out behind them, and while the screw-head slots didn't wear they look like they easily could. I tried using the little tool with the phillips head that came with it, but I didn't like it so I used my leatherman to take out the screws. It worked fine, but I just don't want to wear out the screw heads and eventually not be able to get them out. Are replacement grip screws readily available? Thanks for any info.
