This is a picture of the feedramp on my M&P Shield. It has a ton of horizontal machine marks on it. On my other M&Ps the feedramp has been sanded/polished so the machine marks are gone and the feedramp is very smooth. If I run my finger nail over the ramp I can easily feel the machine marks. On your M&P shiled is your feedramp smooth, or does it have machine marks on it? I haven't shot the pistol yet so I have no idea if it will affect the function, but my other M&Ps have very smooth ramps. I did the best I could with the picture, but the feedramp is pretty shined up so the reflection makes it hard to take a pic of it. It is shiney, but the machine marks from cutting in the feedramp are all there. The dark areas on the edge of the feedramp aren't really there, it is just an effect from taking the picture and the light. The complete feedramp is shiney.
