A wise person only needs a small weapon that will fit in coat pocket and then used as only a very last resort.

Lot's of guns and bullets is about weakness and fear, not protection.

A lethal weapon is something that should only be used when all other options are gone and even then after much deep inner thought and mental suffering.

In Truth, taking the life of another can almost always be avoided with wisedom and disipline. But, if it must be done, then do it with honor, compassion and privately.

But, you decide for yourself.
