What works for me and this applicable to all semi auto barrels, is to first polish the feedramp and throat with 400 or 600 grit wet/dry paper, back and forth several times. To get inside the throat, wrap a piece of the wet/dry paper around a pencil or suitable size dowel. Afterwards, do the same thing with 1000 or 1200 grit wet/dry paper. 'Final step is to polish at medium speed with a Dremmel, FELT bullet tip and Flitz polishing compound - again, the feedramp and throat. The goal is to polish NOT to take off metal or alter the geometry of the feedramp in any way. Polish to a high lustre and clean the barrel of all residue. With larger caliber guns, feedramp and throat polishing comes under the heading of optional assuming the gun feeds, fires and extracts with no problems. In these little guns, where tolerances are tight and there is not a lot inertia to drive things home, polishing IMHO is very important, easy to do, and will not harm your gun in any way.

No fluff and buff required with the P380.

I tend to sell and buy whenever I have the urge for something else....one of these days I'll learn my lesson and keep every gun I buy instead of selling or trading ;) - but of all of the PM9's I've owned, the first thing I do when I get it home is to take it down, clean it then hand rub the barrel (both feed ramp and complete outside) with Flitz to get a nice smooth polish to it. I do not own a dremel but elbow grease works fine for me, and I have never had any functioning problems with any of them. I plan to do the same with my P380 whenever I do eventually get one.

I am exactly the same way cal and we both need to undergo the same therapy -buy, sell, trade, lose money, enough already! LOL.

And yes, you don't need a Dremel to polish. Good old hand energy will do the trick. With the wrong attachments and in the wrong hands, a Dremel is more dangerous than a nuclear Iran.

Using the same technique, you can also polish the P380 barrel hood if so inclined.

Excellent suggestion to do a little polish on the ramp and throat. I do have a Dremel and use it with the cotton tip and special polish compound for feed ramps. The fine emery on a pencil works best in the chamber throat.
Thanks for posting the suggestion.

my dremel cotton tip works perfect in the chamber even. Mine out of the box the feed ramp was mirror perfect, never seen such a perfect feed ramp. the chamber looked as good but I gave it a polish anyways, as I did the entire outside of the barrel and chamber. shines like a diamond in a goats a-s. Has to be smoother IMO.

I did some internal rail, barrel and slide polishing using a guitar fret polisher! It's like a pencil eraser that comes in different grits. Worked really great!
