I have to mill off the front sight ramp and cut a new dovetail because it is about .100 too high, then just a little more work on the breach plug and it is done. I fired a few primers in it and the fat fireing pin on the Huntsman frame works fine. I did have to machine out the inside of the frame so the thicker locking lug would fit, but the length is fine and it locks up good. Did you bag a PD? Larry
