He beats around the bush for too long but the point is solid.
Again this is just for your "keep yourself and your family alive in the face of hostiles" guns. For the work of staying alive by eating, a 9mm handgun isn't that useful unless your plan is to rob your neighbors. So yes, smart to have a .22 for small game, a shotgun for birds and something that can reach out at distance for deer or foreigners wearing blue helmets. Use your own discretion and best judgment.
This isn't playtime, your guns are a critical tool to keep you alive. Be smart in your arsenal.
