I had the same issue. Was using a CZ 75 P-01 love that gun, still use it for HD. But in the street I feel more comfortable with the 45 ACP. Thursday picked up a Bersa Thunder 45 Ultra Compact Pro. Haven't had it to the range yet, but the reviews on it are very good. 3.6 inch barrel, 7+1 for the mags, yes I know I am going down in the number of rounds but just carry extra mags.
Excelent fit and finish for the gun, alum frame and steel slide in a nickel finish, nice looking two tone effect. It is not a Kimber or Les Bauer but at half the price it really is nice. Pistol grip is that of a compact (little short) but does not print when conceled, double stack mag makes the grip a little wide but feels solid in the hand. Excelent trigger a little heavy (about 10 lbs on double action) but it hasn't been broken in yet. Clean crisp let off without any grittyness and I love that front sight (huge white dot).
I compared it to my CZ P-01 and they are exactly the same size with the exception of the pistol grip being a little bit shorter.
If your looking for a CC 45 ACP you may want to look at one of these.
