I agree with all these guys. I carry a G19 with a spare mag on the belt (31 rounds total). If you can conceal it ok, I would go with the double stack. The "printing" is caused by the grip, once you put a grip extension on to carry extra rounds, you might as well have the double stack larger grip. Just my opinion, it all depends on what you're comfortable with. Also, this mid-size gun is a great all around gun for ccw, target shooting, and home defense. Just fun to shoot and relatively accurate.
