Yes, the very early Sigs had some problems. That was fixed years ago. Nothing wrong with the SW but I carry three 1911s regularly:
Les Baer Stinger
Ed Brown Special Forces 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.
no guns = might makes right
