I like barrels on the shorter side. I'm thinking about a 10.5 barrel, so a pistol build for now. Primary use would be home defence, general defence. I don't want to go too short on the barrel and give up power, but as far as I can tell, losing the 2" a2 flash hider gives up nothing on the practical. Would no middle device be louder, more confusion in a enclosed space? Would it have more flash as viewed by the shooter? It is my understanding that a flash hider is designed to obscure the flash from the view of the target, not the shooter. Are there any other considerations I need to think about?
