but not once Ves but twice. Once that I picked up here the other time in the Female Thread. One possibility is that it's the photographer but if so Why. In the other shot it could be for face but this is from the rear. so that's not valid. The only other would be signature that this photographer poses them for "art's sake". which is ridiculous. only other thing I can think of is that this is a actively taught technique and based on the fact that both photos show it, perhaps Actively qualified.
Check out the 7th photo in post #1646. We get at a least a dozen SWAT holding the hand gun properly. So it's 12 vs. 2. The odds is on my side
I honestly think this one-hand thing is an anomaly. I only had to go back one page to find photos with people with good stance. If you take some time and go back some more, you will see that people use the correct stance in ALL the photos you can find.
I just randomly picked a page and found another one, third photo in post#1599 (page 107) , again good stance.
5th photo in post 1166 on page 78, good stance.
