The 1911 platform is my all time favorite pistol! I own a bunch of 1911's (mostly Colts) and in 3 different calibers, (45acp, 38 Super, 22LR). My 1911 Colt GCNM is probably my most frequently shot handgun and I don't think I shoot any other handgun as well. That said, I do not carry a 1911 for EDC/CCW. Too heavy, to large, to "catchy" when carried cocked and locked and to me a 1911 is either a duty belt or garrison type belt pistol.
I purchased my very first Colt 1911 back in the very early 1980's (a Series 80 Gov't model) for the specific purpose of carrying it. Well.... I carried it for all of 2 weeks and decided it was not a carry gun for me. I could not walk 10 steps without hiking up my pants and it was just way to bulky and heavy IMHO. I still have the gun and still shoot it - but I never carry it after that experience.
Even if you get an alloy version and the size and weight are a bit less, it is still too bulky, heavy and large for a CCW IMO. In today's day and age there are much better choices for a concealed carry piece - at least for me. I still love 1911's, own a bunch and still shoot them more than any other hand gun - you just won't ever find one on my belt as an EDC piece.
