I never cared for the ambidextrous safeties on any 1911. I found, for me anyhow, it was too easy to wipe the safety off in everyday carry. A good holster will have a detent in the leather/kydex that cradles the thumb safety when it is engaged. I either had these ambi safeties changed out to a single or had the lever ground off smooth. For sure, I agree 110% on a lot of training with a 1911. I love them, but since I had that joint replacement in my gun hand, I found the Glocks wider web more comfortable, even on my 10mm. Good luck to you Pard.
PS I carried Buffalo Bore 230 +P fmjfn in the mountains in my Kimbers. Never had to use them, but they just made sense to me.
