There is no way of knowing (for sure) short of actually experiencing needing to fire the next time I carry my 1911 but I don't think I am going to forget. I've handled, shot, competed, and practiced draws and dry firing with the Hi power and 1911 so much, I don't think I'd forget their manual of arms. I could be wrong but I don't really worry about that.
I seem to recall (during the last range session Tuesday night) that I instinctively dropped a 1911-type safety with my left thumb,
while shooting my Kahr P9 Covert.
That may not be a bad habit to have considering my somewhat varied carry battery selection.
Now, what I did discontinue, was having a Browning BDM as part of my home defense ready alert. For those of you not familiar, the BDM's safety/decocker worked
totally different from a Browning HP/1911. So pushing the decocker down actually put the weapon onto "safe." I retired that otherwise fine design to the safe.
