Put a handgun in a fast-open safe by the bed.
Duh.
which safe do you recommend?
yeah, that’s the best, but having your keys and your cell phone and your wallet right by you are good for 1)pushing the alert button on the key fob; 2)calling 911 as they try to break in; 3)have your stuff easily at hand if you have to bolt out the other doors or windows in your home if there are just too darn many of the bad guys to hold ‘em off and keep yourself, your spouse, your kids safe.
Also, having dogs that bark and won’t back down from strangers until they are commanded is good.
My grandmother didn’t have all this stuff—she just slept with a small black iron skillet under her bed. She said she could maybe wallop someone and give ‘em a big goose egg on their head! :)
