If I was going to buy a full size .45 I would get one of two choices, plus an honorable mention:
1) Glock 21. I used to have a Gen 3 that I carried for work, and I absolutely loved it. Would get a Gen 4 if I got another one. I put thousands of rounds through that gun over the years, rock solid, not one malfunction of any kind.
2) Walther PPQ 45. I have a 9mm PPQ M2 that is one of my favorite carry guns. Best ergos of any gun I own, just a smidge better than my P320. The quality of materials, trigger, and fit & finish, are the best of any polymer gun I've owned or even handled.
3) Honorable mention: M&P Shield .45 - while this doesn't fit your criteria of being full sized, it's the one .45 I would be most likely to buy next, just because I wouldn't hesitate to add it to my carry rotation (as soon as I got the holster and mag carrier for it). The other full sized 45's I mentioned I probably wouldn't carry due to size, thickness and weight. The Shield 45 may be the perfect carry 45. Every review I've seen has been very good to glowing. And I've already had a 9mm Shield for several years that I carry probably more than any other gun I own.
Best of luck on your search.
