For those who are looking for a Concealed handgun, here is a great chart that compares the most popular carry weapons including size, weight, and price. http://www.mouseguns.com/PocketAutoComparison.pdf
What I love about this is each gun has a hand graphic that shows the relative position of the shooter's hands based on the weapon size.
One drawback, no distinction is made on quality. Everything from low end Jimenez to high end Walthers are included.
