I don't own doubles of the exact same model (except for a pair of SW Model 10s) but I do own multiple 1911s set up in a similar way which I carry.
Jim's Rules of Carry: 1. Any gun is better than no gun. 2. A gun that is reliable is better than a gun that is not. 3. A hole in the right place is better than a hole in the wrong place. 4. A bigger hole is a better hole.
