The best weapons for self defense are those that are convenient to carry, easy to use, and are effective at forcing back an attacker. However, there is no single weapon that will work best for all kinds of situations.
Some will be more effective for self defense while you are outside your home while others would be better when you are at home. It would be up to you to take into account the advantages and disadvantages of each weapon and decide which to buy.
This is a good weapon when you are inside your home or outside. This may not be suitable for defense when you are in public because you can only carry it legally if you have a special permit. There is also a need to take some courses on firearms safety. Nevertheless, a firearm is an effective and powerful weapon that requires minimal strength and training.
One gun is good, several are better. A combination handgun, carbine, rifle and shotgun would be the ultimate arsenal for self defense.Once you decide the type of gun is best for you, it is a relatively straightforward process to choose a caliber or gauge of ammunition that will fulfill your needs for protection.
Make sure you are aware of federal and state gun laws before you purchase a weapon.
• Small knife & Big Knife
A small knife may be a good weapon for use outside the home and a big knife for inside. A small knife is easier to conceal it and it is convenient to carry. However, you need to make sure that your knife is easy to open in case of an emergency. It could be used as a quick weapon that can surprise your attacker. This will allow you to escape while he is temporarily stunned. However, this will require some training for you to effectively use this kind of self defense weapon.
Also most all states have laws for concealed weapons. Please be aware of the federal and state laws.
• Mace and pepper spray
These are non-lethal weapons for self defense but you will also need to get some training to ensure that they are effective. The chemicals must get to the eyes of your attacker to allow you to escape. Some practice may be needed to ensure that you can aim the spray properly. You will also need to hold the spray bottle in your hand while you are in a neighborhood that could be dangerous.
