There are lots of good options. For me, the Sig full size 1911 is one of my favorite full size guns in .45. I am also a fan of the CZs and may pick up a SAR K2 one of these days. I had a CZ 97B and that was really nice, but it was the biggest gun I owned. In fact, it was too big and I sold it because of that. The K2 looks to be sculpted a bit better and has 4 more rounds on board.
