Not much experience with the 1911 of any size.
I too was warned against anything shorter than 4". But, after reading the reviews and others who onwn one, I bought a 3" Colt New Agent.
Currently have only 200 rounds of various FMJ through it, but I have to say that I cannot seem to make it malfunction. I do not have strong hands or wrists. Two handed, one handed, slow or as fast as I can pull the trigger - it has been flawless. I love it!
