Is this going to be your self defense gun?
Have you shot many different semiauto handguns?
Did you have good success with any of them as far as accuracy goes?
If the answer to the first question is "yes" and the second is "no" then it is best to talk about basics instead of make/model. If the answer to the second question is "yes" then look for a gun with the features you want in that "family".
The "basics" are, fit the gun to you and not you to the gun and pick a gun that goes "BANG" when you want it to. Fit means find a gun that has a grip angle that allows you to point the gun naturally so that the sights come right up to your eye properly aligned without having to change your grip or adjust the angle of your wrist. Find one that has a comfortable reach to the trigger and has a grip width that doesn't require you to throw your wrist out of alignment with your forearm to point the gun at the target. Find out what grip angle/reach/width fits You, then you can find what steel/poly gun has the features you want. Then you can look at reliability and ability to feed ammo.
If it turns out you point a CZ better than a 1911/XD/M&P you'll find that you will be comfortable shooting heavier recoil ammo out of it than a gun that doesn't fit you as well. If the Glock fits better than the CZ, the same applies. If you don't like any of those, look at the newer generation of handguns with interchangeable backstraps that allow you to alter the grip angle to fit You. Guns like the M&P, new XDs, even the Walther may give you the fit and features you want.
No one make/model of gun is "the right gun" for everyone. Make sure it fits you and you're gun will be right for You.
BTW, I fit the BHP best of all, but the 1911 is close enough that I've retrained my body to shoot it naturally and I'm thinking about a new poly pistol that has the grip angle of the 1911 to replace my old P12 (which has had 10,000 rounds through it without a hiccup).
