Thinking of getting a handgun for home defense / plinking. I'm mainly looking at a 1911, but not sure where to turn? 45 or 9mm (in case my wife needs to use it), What make Kimber, Glock, beretta or ? There are alot of choices and would appreciate a little help. looking for a middle of the road $, around $800. I'm only 5'9", so I'd be looking for smaller grips also.

Thanks for the input
