I think your onto it, it's just a matter of getting the proper detent and the right contour to get there.
Personally now that your an expert at 1911 safeties I've never been fond of ambi safeties unless your one of the 3% of the population that is left handed.
You can toss the ambi and purchase a regular single side safety and if you get a good one the detents and contours should be right where they belong.
Many prefer the ambi especially if they are doing shooting games where they have to weak hand etc.
And if you get yours where you want it, it's perfect, forget everything I said above.
Speaking of 1911's, I just swapped out some too thick grips I made on my Wilson for some super thin grips I made years ago, had to swap to the short bushings which went fine which I was thankful for. Whole new gun, feels so incredibly much better, my day is complete and it's not even noon yet.
