I'll let the pictures explain the problem for me... keep in mind this is my second gun model (any critique is welcome :P) and i will be baking it down onto a low poly version when it's done











I added some extra pictures just to show off what I have so far, but I am mainly concerned with the issue pointed to by the red arrows

Hey man, im pretty new to Sub-D myself(ish) but try doing what i have illustrated in the image, the smoothing may be from the n-gons not having any support, and going a bit ape-shit :P

If that doesnt do it, you may need to chamfer the edges that run around the holes, or add in control edges around the outside, but try what i have illustrated first.

Not the prettiest wire but it worked good for me.

put a Plane on the center, Subd it to 1 or 2 iterations, and get rid of all the triangles.
