GBA:  With all due respect, I looked at the pictures above and do not know how anyone could tell what caliber that weapon is, to far away and bad angle.  Anyway, even if its a 22 LR its a deadly weapon.  And yes, I have had firearms my whole life.   I have Lotsa firearms.   GUNS  and AMMO FOREVER.  Why?  Its Security against the CRIMINALS and WHACK'O'S.  

Ex.     A guy came to my front door and knocked on it  this last Mon.  I looked out the peep hole and did not recognize him.  I had my 45 behind my back and I opened the door.  This guy was high on METH or HEROIN.  I asked, can I help you?  He started to put his hands in his pocket and I said, keep your hands out of your pockets.  He continued, I stood behind my doorframe for cover, my weapon pointed at his chest.  Out came his hand and it had a  plastic pill container.  He opened the container and started popping pills right on my front porch.  I told him to leave immediately and he did.  I called the Police and they arrested him
