Your demonstrated "Rambo" mentality and several comments made in other post of yours in this thread and else where. I think you need to take a good long HARD look at what is truely involved in being a RESPONSIBLE gun owner and carrier.
Look, I don't know you through anything more than what you write here. I took some time to reread several of your posts from the last several months. I think you have amply demonstrated why 21 is the minimum age for hand gun ownership. I have grave concerns about some of your commentary in this thread. You've shown that you truely haven't given sufficient thought to what it really means to be carrying a weapon all of the time and that does indeed scare me.
I'm not saying you're a gang banger or other type of miscreant, you simply need more experience in life.
It's all fun and games until someone starts throwing bullets!
