I’ve probably mentioned this before, but here are a couple of excellent websites to learn not only about concealed carry and defense with a firearm, but why you would want to consider it.
Oleg Volk’s A Human Right
Kathy Jackson’s Cornered Cat
Both of these sites are really excellent if you are thinking about concealed carry as a method of self defense. Oleg Volk’s site has some great insights as to why you would want to. Cornered Cat has the best overall take on the subject I’ve seen anywhere; not only why, but a great wealth of detail about the practical aspects.
It’s worth revisiting. If you have never given this any consideration, check them out. Highly recommended.
