I have been finishing a fluff n buff on the P32, and I think I have all the rough spots smoothed. It was extremely hard to rack the slide when I got it, and so the first thing I did was follow the FnB guide here. But I didn't do the barrel thoroughly enough, so I went back and really smoothed it out, everywhere, and the slide too, and now the slide racks with ease. The barrel was really rough on the outside, and I kept finding friction spots. Now the exterior of the barrel is polished, inside of the slide is smoothed, and chambering a round is a breeze.
The trigger I left alone for the most part. I found a rough spot on the bar and smoothed it a bit, but left the rest alone, I did put a light grease on the aluminum frame under the steel bars on each side (Mobil synthetic grease with WS2, tungsten disulfide, mixed in). The trigger seems smoother, though not any easier to pull (which is good, I don't want a light trigger in it).
I plan to get a couple more mags for it, and just enjoy some range time with it. I like the soft-shooting caliber, and I may get a .32 revolver to play with at the range too (327 Fed most likely, as it shoots all the .32 revolver cartridges).
