So Nedl and hiroad only wants big magazine to avoid and defend against a tyrant government. Don't forget when this happens you will outgunned, your little .223 pea shooter with large magazine against a "gatling gun" at 50,000 rounds per minute. How about a Drone that drops one of those 500 pounders on your head?
When you are talking even a SWAT team against you 99 times out of a 100 you will loose. A large magazine isn't needed. Instead of fighting for your freedom sometime in the future, how about fighting to prevent it now?
What is needed, mental health, proper parenting, and love for each other. Use guns for quick relief and you will get lead poisioning.
