I agree I'd take a full-size Glock over a full-size steel SIG any day. It seems a no-brainer for LE/military. Two extra rounds in the mag, ten ounces lighter, softer recoil from the flex in the frame, no hammer or need to de-cock, consistent trigger pull every time, and half the price.
Just noticed this from the picture above:
Notice it is cocked. His finger is not on the trigger so he's not dry firing. The P226 has no external safety and is not safe to carry locked and cocked :G I guess since it's not in a holster maybe he has pulled it out, unloaded it, cocked it, and is about to dry fire it on single action for some reason, but I do suspect he has been carrying it like that.
