Needed: 100% legal (own, transprort, use) weapon for self defense in all 50 states...
I have been reading here for a long time, and have found almost every answer to every question I could think of asking. I do, however, have a unique problem which has led to me joining the forums. Given the nature of mine and my wife's work (travel nurses) we will be traveling from state to state about every seven weeks. What I need is a weapon that does not require registration or permits that can be taken to any state and used in a self defense capacity. I also need it to be concealable if possible, however, a larger "whatever it is" is fine for the apartment.
I figure some demographic information would help in the weapon's selection. I am 6'4" and reasonably strong. My wife is 5'3", and weakish. I would like something for her to use as well. So far I've found that garden tools, sports equipment, and some general contracting tools seem to be legal. I would rather have something that fires a projectile as I have some skill with firearms, and would prefer to keep my distance from an attacker.
Any advice or help would be greatly appreciated!
Thank you all in advance:)
