There are many options and it will help ease worry and concerns and worries about any wrongful problem happenings of someone that chooses to use force by choosing any weapon; especially a firearm.
Study your state laws, safety first, dry firing (some people hate that work), but it will help in your accuracy, gripping a firearm of your choice, and confidence too. Things may get heated worse, but you are going protect your love ones, and yourself first in the proper places; NOT in a TARGET Department Store at 2:00 AM, with a AR 15.
Best to be your best and train always some way and you will become greater and your family will be proud of you.
