Gordon,
I have a 9mm, and can handle it well, and quickly if it jams( not often but it has) and that my friend is NOTHING to rely on when it comes to your child's or your safety....it just does not suit my purpose if I ever have the need. My feeling is that if the need ever.... God forbid happens, it will be immediate and I will react on instinct of years of assessment of an individual situation, mindset and shooting ability. I could do that with the 9, just choose to carry a revolver. Much more security in the field (gotta have a speedloader just in case). IMHO
