Found an interesting article on the logical selection of a handgun for self defense.The handgun selection process was made for home defense as well as carry for both he and his wife.

I have a home defense gun much larger than his selection with an attached laser/light source and carry smaller lighter carry guns.Guess I obsess/specialize needs--

This fellow is very practical,analytical, and thorough.
I like his handloading projects/articles as well.
