Although my P380 worked perfectly (and continues to do so) right from the start, racking the slide has been a little rough, a slightly gritty feel is the best way I can describe it. A very easy and safe fix, is take a piece of 800 grit wet/dry paper and go back and forth on the rails and on the top of the frame. You don't need (or should) to apply a lot of pressure, just enough until the surface areas feel smooth to the touch. You will be surprised at how much smoother and "cleaner" your slide racks back and forth. 'Strictly optional but along with polishing the barrel feedramp and throat, it's not a bad idea. Your gun will go bang regardless but the slide and frame will mesh smoother and have a "cleaner' feel if you do the lightest of polishing. Enjoy.
