Edm, On my first long gun, I positioned the tail of the lock too high. The gun shot great and still handles and shoots great, but every time I cleaned it, that lock position would haunt me, and I even invented a few vulgarities to describe what it looked like to me. As far as I know, no one else noticed it, but I didn't make the thing for 'no one else'. I did plane off the lock panel, reposition, re-inlet the lock, and refinish the whole gun. Today, even I have trouble finding the exact line of my scab. I learned a lot on both the first and second go around, I learned more on the second. What ever you choose to do, best of luck with your decision!!!
