I did watch that, good stuff. I kinda like the style of the 709 better, more streamlined. Plus I believe the G2C and the G2S are pretty much the same physical size, just different mag capacity (might have mentioned that in the video).
We also added thee G2S to the collection,everything is same size as the G2C except for thinner grip and magazine capacity ! It does fit better in the waistbad especially when sitting in the car.I recommend you get them both !
