Help, a little trigger advice puhlease ...

The nose of the long arm of the cocking piece should be rounded. As to what radius........., well, in simple mechanical terms, it could be the radius of the centre of the axis pin hole to the end of the long arm but I always make a neat slightly smaller radius. As JM says, all the working you do must be vertical/top to bottom on the sear and cocking piece

Now that's new! It makes sense, but it would be REALLY hard to detect over such a short distance as the face of the sear. So, a stoning jig w/ an undersize locating pin which bears against the rear of the pivot pin hole ought to do.

I reckon hand stoning would naturally tend to do the same, but it would be real easy to go too far.

I believe the US '03 Springfield forum guys had a much, much larger version of this same debate not long ago.

I will comply in the future!
