I have messed with and owned all sorts of 45 autos including the little Detonics and while I have a stainless Colt Commander, (one of those Chip McCormick things from the Colt custom shop) I carry a full sized 1911 Kimber. I have found that the full sized gun actually carries better than the smaller guns especially if you just want to put a gun in your waist band and go. The longer and heavier gun in a tense situation will allow to get back on target much faster shot to shot than the shorter one and the bullet will go as much as 75 fps faster out of the longer barrel giving the bigger gun more stopping power. I also have a Wilson KZ 45 which has a polymer frame and it is a nice piece but it too suffers from being too light in weight especially as its 10 shot magazine runs out of ammo. That is my opinion which to some could be considered worthless.
