Would a 3 point sling be viable if a shotgun was my primary long arm? Scenario: Offensive/Defensive. In a group some have carbines some others have shotguns and one long range rifle...Just explaining why the shotgun is my primary. I will/would put the time in to learn how to use it. My question is would the 3 point sling interfere with reloading from my side saddle and operating the pump?
