Talked with a friend who has back trouble. He mentioned that a 5.7 should be a lighter PDW to carry and less straining for his crushed back. I told him to look into really lightweight AR15, but he said he would like a lightweight 5.7 style pistol in a brace or AR15 pistol. Bullets are lighter and easier to carry. I don't know much about them so I thought to ask here.
