So I bought an almost new Kel Tec P3AT .380 on this forum. My first hundred rounds through it produced more than twenty malfunctions. After research, I put it through a "Fluff and Buff" which mainly consisted of taking 400 and 600 grit sandpaper to all the surfaces that rubbed on one another. After completion of this treatment, I ran 150 rounds (I would have run more, but .380 is difficult to find these days) through it with no problems at all. It's a different gun.
Just thought I'd share.
