I too have big hands and have looked for large handled handguns. I believe the CZ 97B is an excellent choice. The Witness .45 is a good second stringer for this. I had one in wonderfinish that I absolutely loved and hated to get rid of. However, if you ever have problems with the gun (and a few people have), EAA can be a pain to deal with. Another choice may be a CZ 40B. The handle extends down to end evenly with the magazine baseplate. Of course, this is more for wider hands with normal to slightly longer length fingers. And the used HK .45 double stack that I tried at my local gunstore fit me like a glove. Too bad I have fundage problems at the moment, or I'd have picked it up. (~$650?)
Good luck
