[J.A.Sucker]

I have a glock 23 (40 cal) and it's a great weapon.

However, for home defense, a revolver (S & W .357) is best. You pull the trigger, it goes bang. That's what I want by my bed at night.

Also, glocks have pretty light triggers, and many people don't like that around the house, and probably with good reason.

Load hollow points no matter what caliber you get.
