I'm thinking about having subject safety installed on my 5" '91A1. Does this installation require any milling or significant modification? After I got an Officers, I began to like the idea of the ambi.

Requires some fitting of the right side grip. That's all.

There also may need to be some slight fitting of the safety "lug" to sear.

...um....yup. I forgot that...... If you're replacing the left side too, you have to fit it as well.
