It's very easy to eliminate the high edge right at the frame. Five minutes of sanding is all it takes. I don't know why Pietta leaves that edge. The square angle there at the frame is perfect. Once you sand it down, it looks so much better.
There are other small problems though that you can't fix. Looking at the navy grip, you can see just a bit of brass frame showing on the inside curve, along the right hand edge. The grip panels needed to be just a tad wider there. Still for the money, I think the Piettas are a great value.
