Sure hope the Military version has lighter trigger than the civilian Sig P320.
First thing I did was change it out for the Grayguns trigger, which comes in at about 5.5 lbs.
I have the full size RX and found a great CCW holster for it, and now its my dream package.
Was carrying the Sig P220 SAO Carry (.45), but this 9mm set up is great.
The trigger was mentioned, as well as the addition of the laser. And, iirc, left or right ejection, lighter materials, etc. Maybe a round or two more in the magazine
Shoulder to shoulder firing, it was faster with better grouping.
