I agree with the above posts 100%.
Never go lighter than you feel is safe for you...and be honest. I've ready your posts, 45R, and can guess that you are a reasoned man of sound mind...so no worries.
I also wholeheartedly agree that a smoother trigger with no creep, a clean break, and no grit will "feel" lighter than it actually is.
That said:
I use a 1.5# trigger on my bullseye 1911's.
I use a 2.75# trigger on my competition 1911's (action shooting, IPSC/USPSA). Most the grandmasters at my range use a 1.5-2# trigger on their race 1911's.
For carry/HomeD, I'd prefer a DA/SA, but if 1911, then at least 4.5-5# trigger for me.
Cheers!
