All good points from everyone.....but I'm calling VisibleGreen out for failing to read my thread starter post. I have all of the above and then some Just in case anyone missed it the first time around, aside from my carry permit and a variety of firearms, I also haveWell firstly a knife is extremely dangerous in a fight. Not sure why you said it isn't. Secondly with the suggestion, a strobe flashlight is very easy to get a hold of. PM me if you want some suggestions. That would be better than a laser. A laser has no added benefit in a fight. I don't get why you're still focusing on it.
The usual stuff like tazers, pepper spray, bright flashlights and heck even hand thrown bolas are good enough. If you want something crazy why not a paintball gun
plenty of less-than-lethal "options" as well. Here's the short list:
Taser X26 (legal for civilian to own and carry with FID Card in my state)
Tiberius Arms Tac 8 (w/Pepperball Kit) not legal for me to carry
Various Pepper Sprays, up to 1lb can of Bear Spray and 9oz can PepperGEL
JPX Jet Protector (A Tazer substitute, fires pepper spray 20' @ 400mph)
Lots of high power, quality flashlights including my favorite, the
Surefire UB3T Invictus (1000 lumens and strobe mode)-will mess you up!
I also have firearms in the home, I tend to lean towards my Remington 870 short barrel and have a variety of ammo including these special rounds Multiple Impact Ammunition Which if you haven't seen...you have to check it out...uber cool!
