The rule of thumb seems to be the smaller they are the better they carry. I do carry a full size 1911 a lot, you need a good belt, a good holster and it can be done and you can get used to anything, but the bottom line still is, less weight and smaller feels better no matter what anyone tells you if you carry a lot. I'm not sure why some of us carry a full size 1911 a lot, I guess in my case it's because I can shoot one really well and am real confident with it, it's not because it's the best carry gun. I have a good belt and IWB holster that works well for me considering the size and weight.
