..2 minute video on U.S. Department of Veterans Affairs site may help...type in "gun locks"..
.Three of my Vet friends have pulled the trigger on themselves...no coming back...I have taught my children gun safety from when they was little guys...I always had loaded guns around me, ever since I was a little guy and still do...I have no intent on Suicide...just be safe minded ya'll...
A gun lock would not keep me from killing myself, if that were the intent. I worry about the other stuff...Government intrusion, by knowing who got a lock.
I've been asked many times..... get the same answer......no. I don't want some government idiot knocking on my door wanting my guns.... it's none of their business.
