When I was in a state where I could carry, I rotated between the Beretta PX4 SC (40) and LC9 depending on weather, mood etc. While with the right holster both were discrete and comforatable, but carrying two 10rd PX4 mags was very bulky compared to the LC9. (The PX4 SC in 9mm is a 13+1). I am also 6'3" so it might be a little easier to conceal for me compared to someone else.
