Two More Weeks...

All the brands you mentioned make good compact guns, pick out the one you like best. I had a full size CZ-75 years back and wish I never got traded it off. It was a very well made gun and was very dependable. The price was not hard to take either. The 85 series are said to be an improvement but I can't remember the differences well enough to give a yea or nay. SIG has several compacts and in varying sizes. The only one I have heard bad about was a Pro (I think that is a SIG gun, if not disregard) in 40 S&W. It was a problem out of the box and actually got worse the more it was tinkered with and fired. That is the only Pro that I have seen so can not say if it is indicative of all Pro models or if that particular gun was a lemon. Otherwise I think well of SIG, I have a Browning marked 220 that I enjoy shooting and have shot sevweral other models in the past. Kimber is pretty proud of their guns and carry a price tag to match. I think Springfield is just as good quality but at a cheaper price. The only caveat I have about short 1911s of all makes is that the really short ones like the 3"-3.5" barreled Ultra Compact can be picky on what ammo type it will feed. My Springfield Ultra Carry ate all types of 230 gr bullets except Wolf, but did not care much for 185 gr bullets except for Silvertips and Golden Sabers. The Federal 160 gr Personal Defense loads were the worst by far in that gun. Except for a Kel-Tech P-40 as an ankle gun I have gone away from the typical subcompact guns. The intermediate duty guns with 4" barrels and full size grips are as easy to conceal with a good inside waist band holster carried just behind the hip and a little thought to clothing and are much easier to shoot well. I've been carrying a Service model XD-40 quite a bit lately and no one has commented on it being seen. I've been wearing shorts and T-shirts or button down short sleeved "fishing" shirts so it isn't like I have a lot covering it. Body shape is important to an extent but there are few that can't hide a gun with a little bagg clothing. Some bodies I don't want to see carrying a gun, others I wish they would carry a howitzer if you know what I mean.

The CZ-75 is a pretty nice gun. SIGs aren't bad either. But if you want a fantastic gun. I'd go with the H&K P2000. This is, technically, a compact, but the grip is a "full size". The gun is extremely comfortable, extremely accurate, and reliable. I also own a H&K USP, if you want a true full size gun, the USP is incredible. Another gun to consider is the Glock 36. Which is a .45 caliber, but it is fantastically small, while still comfy.
I have large hands, so I have to be pretty particular about which guns I get. I prefer large frames when I'm choosing guns.

As for caliber, the 9mm is nice for target shooting, it is cheap, abundant, and allow better penetration power. The .40 on the other hand is heavier, will reduce the capacity of the gun, and has a greater kick. But when you are talking about defense (home defense, or person public defense) penetration isn’t always good. Over penetration is huge factor to think about. If you have to shoot someone will the bullet travel through the person and beyond? The likelihood of someone having body armor in public is extremely unlikely. .40 FMJ bullets have about 20% more stopping power over 9mm FMJ; but .40 JHP have about 50% more stopping power over 9mm JHP.

So when I finally decided on a concealed weapon for carry, I picked myself up a H&K P2000 .40 with Hydra-shock JHP. With this setup, you get 12 bullets (instead of 13 9mm), you get an extremely reliable and accurate double-action small frame pistol all for under two pounds.
