I know I am a little late, but I carry a shadow 2 off duty 90% of the time. My company requires me to carry a Glock 22. I am use to and prefer carrying full size guns for various reasons.
The gun is heavy, but not as heavy as my duty gear so I do not notice it as much. I am not a large guy at 5'8" and 145 pounds. I do not open carry when I am off the clock and I have had no problems concealing any of my large handguns. I also pick my wardrobe exclusively with concealed carry in mind.
I carry my shadow 2 (9mm) in a red hill tactical IWB holster in condition 1 with a 15 degree forward cant on my right side. I also carry two extra magazines in separate pockets on my left side. My gun is loaded with 124gr +p speer gold dot with a spare magazine containing the same ammo. I also carry a third spare loaded with 90gr underwood extreme defender +p+.
