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.
