A few of the guns i have been looking at:
Kimber Tactical Pro II (Its expensive, but i really need to shoot one of theses)
Para Ordinance Tac-Five (Not as expenisve as the Kimber, maybe a good option between the three)
H&K USP Expert (Maybe just the USP)
What would you suggest and why?
Well the first 2 out of your 3 choices are Colt 1911 pattern handguns and that is the type of gun that I prefer.
I own a couple Paras, never owned a Kimber but my observation of the two is that the higher grades of Kimbers are fine pistols, very much like artwork. Some friends report them as finicky when new but after they are worked out they are great guns. The Paras are more of a duty grade weapons with a little less fluff and polish.
My general observation is that the tried and true Colt 1911 type guns are easy to carry, easy to shoot and absolutely reliable if you give them modest care and cleaning. I own a dozen or so 1911s of various brands and find them to be the easiest style of pistol to shoot accurately. I've got them in 9, 38 Super and 45.
There are people who criticize 1911 pattern guns, I don't know why. They are the choice of SWAT, SEAL and SPECIAL FORCES teams, they dominate competition shooting. That says something about the guns for accuracy, reliability and ease of use under pressure. Hey, if someone else likes something else, that is good with me too. Its just my choice and I doubt you could go wrong with either the Kimber or the Para.
