Looks like Siler is a smart-ass leftie seeking attention to me. I can see daylight through Cruz’ gun barrels. I suggest Wes Siler (and his fans)STFU.
The fact you can see daylight through the barrel while facing Cruz is meaningless to the issue of whether or not it’s a good carry technique when there are people behind him.
But its not like the shotgun Cruz held for this photo-op was ever loaded either, so maybe it doesn’t matter.
