I have a CZ40 that impressed me so much, I'm now buying a CZ75. The 40 is a little lighter than a steel framed 75, but can be shot well with a little practice. It carrys a little better than a steel framed pistol though. It was my 1st CZ and definetly won;t be my last. I don't think you could go wrong with either pistol. .40 is more expensive to shoot, but more reassuring(too me anyhow) than 9mm for defense, after years of .45 shooting. Anyway, I give the CZ-40b and the CZ-75b(actual model #'s) both high marks. That said, the suggestion of a .357mag revolver is a very good one! I have a Ruger .357 that's built like a tank, the ultimate in reliability, and shoots anything from lite .38spcl to full house .357mag rounds(awesome power), with .38spcl +p jhp's for everything in between. A good .357mag DA revolver is one of the most versatile guns ever made, and a good used one can be had affordably. Good luck in whatever you chose, and remember : SAFETY FIRST ALWAYS!!!!!. BTW, I'm referring to handling/practices - I ALWAYS keep a loaded gun nearby and have put the time in with my children so they know safety and responsability like my father did with me - he never owned a trigger lock and probably never will. I'm not saying they're bad(I own some), but they're not the "cure all" the libs paint them out to be. Safes are a very good idea, especially for when you're not home. I grew up in a home with loaded guns and have NEVER misused one. georgestrings
