As a Lefty I can state with out a doubt that an Ambidextrous safety is not needed. I own several 1911's and none are fitted with one. I use my index finger to operate the safety with out any difficulty. If it is what you want go and get one but it is not needed.

That technique with
practice, is key. If it works for you,...that's awesome. Getting the safety "off" with the index finger takes practice, as a fellow lefty, I can attest to the "tricks" to get a "righty" gun off safe., Ex. Walther PPK/S, decocker.
Slide Stop on my FN9. The index finger can do many things with practice..and that's the key.
The ambi safety, for me is a natural movement to take off safe, right next to my left thumb on the grip anyway. Their not expensive, and one less movement in a ready position.
Just like standard spiral notebooks. We overcome, adapt, adjust, with practice.
Glad it works for you.
