Glock 3rd Gen vs 4th Gen - Hand Size

[keylay31]

Everyone says that if you have small hands, you'd like the 4th Gen, and if you have large hands, you'd like the 3rd Gen. So I have a three part questions:

1) What length are you hands (measured from first wrist line to middle finger) because I have no idea what "normal" is
2) Do you consider your hands large, medium, or small?
3) Which generation do you prefer (PURELY BASED ON SIZE)?
