Anyone know of a gunsmith experienced in fixing a botched up rear sight dovetail? I bought a slide from a parts bin, which someone had cut for a MMC sight. The problem: the cut wasn't level perpendicular to the slide and so the sight sits at an angle. My thinking is that it's too far gone to be recut, and has to be rewelded, heat treated, and then cut correctly. Also, does this sound too expensive to fix? Should I call it a loss and buy another slide? Any 'smithy recommendations would be greatly appreciated.
