I own a Tactical and a Kimber 1911. They are both outstanding weapons.
The Kimber is a Pro Carry and I carry it concealed almost everyday. It's very reliable, or it would never find its way into my holster. It points very well for me, unlike any Glock I've ever fired. I've got about 15,000 rounds through it and have done a little work to it. The only maintenance I've had to do was a new set of Wolff springs when the original springs started to get a little mushy.
My Tactical is very accurate and reliable. The first group I fired after purchasing it came in at 13/16ths of an inch. It comes with the HK Match trigger, and I've Loc-Tited the overtravel screw in place to avoid any movement which could render the weapon incapable of firing. Since the grip-to-barrel angle is exactly the same as the 1911, I had no difficulty pointing it naturally. Ten round magazines are great. Twelve rounders would be better.
I have a UTL II that I keep on the weapon for home defense, bump-in-the-night scenarios.
It's a little big to carry everyday, but I have a holster built for me by a friend that I have carried it in with no problems. My hands are plenty big enough to reach all the controls without shifting my grip, but I understand that this could be a concern for some.
You have a tough choice if it has to be one or the other. If you're looking for an everyday carrry weapon, I would recommend the 1911. If you're looking for the handgun I would choose if I was going to war tomorrow, I would go with the USP Tactical.
Enjoy whichever one you pick.
