That is always a great option if you are into the 40 short and weak caliber. Personally, I'd like to have a full size Kimber in 9mm. Ten shots with excellent accuracy, and not much recoil to speak of.
You know I don't shoot as much as I used to. To be honest if I need a gun for home defense I think I would prefer my 20g. I am more comfortable with it. Plus the intimidation factor of a shotgun blast I think helps ward off any accomplices
I will have you know I went to the range 3 times since we had our discussion. Today I picked up my new Taurus 24/7 9mm shot 50 rounds and loved it. I actually think I am a better shot than with my .40
