Just how much you want to spend? Any of the name brands are pretty darn good. I have a TRP Operator that shoots great(I don't). I have friends that love Kimber, Baer, Wilson or Sig. Non 1911 like Glock, Ruger, Sig and others are good choices also. If you are going to "carry" a full size 1911 can be quite bulky. The Kimber Solo, Ruger and Beretta 9mm's are much smaller and the newer defense ammo makes them excellent choices. Practice with the gun of choice is much more important than the gun; other than function. The gun has to work and function flawlessly or ???. Wheel guns are a great choice also depending on what you want. I have a S&W R8 357 that shoots fantastic too.
I have heard that years ago 10+ that Kimber kinda sucked but from what I've heard that has changed. Polymer guns shoot differently from steel/aluminum guns so you have to judge that from a personal viewpoint. BRI is pretty knowledgeable when it comes to what he'd use to protect himself and others and has much more info about guns than I do. You could PM him and get his opinion.
Good Luck and have fun; be safe
