I'm looking to buy my second handgun. I currently only have a Smith M&P 9. Now I want a SA/DA semi-auto with an all metal frame and an exposed hammer. I want a 9mm for keeping the cost of range trips down. I had pretty much decided on the CZ 75, but I wanted to throw an open question out there for any other recommendations/opinions on reliable steel framed 9's around the $500-650 range. I'm a lefty as well, so ambi controls are a bonus.
