I have a Ruger MK II and a Ruger Single Six. But what I have found myself carrying when I am out and about is my S & W Model 317 Airlite. It is a three inch barrel adjustable sight eight shot revolver. It only weighs about 10 ounces. I hardly even notice it on my hip. I especially like it when riding my 4 wheeler or checking my trail cameras. And if you want it is small enough to conceal.
It can be shot double action or single action. And the swing out cylinder makes it much faster to reload.
(Luke 11:21 KJV) When a strong man armed keepeth his palace, his goods are in peace:
(Luke 22:36 KJV) Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
