I'm currently researching both the Colt Defender and the Para-Ordnance Slim Hawg (think they're small/thin enough for me to conceal.) I'm 5'6" 150 lbs and both of these models appeal to me in size and weight. I've considered a Springfield EMP .40 too since it has a higher round count/comes with 3 mags but it's slightly heavier too. All three seem to have decent sights as well. I've read good things about the Colt, but haven't ran across much on the Slim Hawg or EMP. Thoughts or experience with any of these?
