It is important to keep guns safe in your home.
No matter what kind of gun you have or what your purpose is for having it there is no excuse, according to firearms experts, for not keeping it locked up.
Every gun that is sold in stores comes with a lock.
The lock goes through the holster and when used properly there is absolutely no way the gun can be fired.
Some manufactures are also making their guns with a lock and key built into the gun.
Without taking the gun apart you simply lock it with a key and it won't fire.
Ranch and Home sales associate Bill Steele said some people prefer to have loaded guns, and if that is the case there is still a way to safely go about it.
"If you feel like you need to have a loaded gun in your house for protection it needs to be on you in person, in your control or locked up where no one else can get access to it. It is a good idea for guns that aren't going to be used for a period of time that ammunition is locked separate from the firearm," siad Steele
Steele said taking away kids curiosity about guns is also a good idea.
After you're done talking about them lock them up in a gun safe.
Some lock with a key, others a keypad and the newest ones even use your fingerprints.
There is a law in Washington State that all safes that can hold a hand gun or long gun are exempt from sales tax.
