Well first off I answered no question I offered?
As far as throw away guns, its not a technical term , it simply means those guns you see cluttered in the display case at the gun shop , with the funky design and weird calibers , no I dont have them in every room , I agree if your comfortable carrying around the house you already have what you need , I carried my whole life, I dont carry all the time anymore ,I dont have to where I live, I can be at the ready in less than ten seconds anywhere on my property! I have 5 acres of land , I am ready!
I dont believe in these little "toys" and thats the main reason , kids will see these as just that a toy , and guns that dont have ammo in the clip might as well be in the trash can!
I do like derringers as long as they are in calibers above .38 , yes I have a thing about larger calibers , Always have ,my 45acp taught me that in a serious way , when a fellow officer was shot , 3 feet in front of me , there was a bullet hole the size of a 45 in the front and the size of a grapefruit in his back , he was dead in less 5 minutes , if that was a 9 or 22 he'd be alive today , I never carried anything smaller than a 45 after that!
That was not my 45 , the suspect found out what 9's are capable of shortly thereafter!
