A safe gun is a HOLSTERED gun. When CCWing keep it there.
He had no call to mess with it. Fortunately he didn't kill is wife or any other unfortunate soul that would have been there (or if the door opened they would have been shot as they entered.)
Been packing CCW for 20 years using 1911, SIG traditional DA/SA, S&W 3ed Gen, Kahr, Glock, various revolvers and never had an ND/AD. And yes packed the 1911 cocked and locked, the Kahr K9 has a very light but long trigger, my Glocks have NY-1/3.5 lb connectors, and of course the revolves are revolvers.
Plus 30+ years of IPSC and IDPA and no ND/AD as well as 40+ years of hunting.
Once I leave the house the gun stays where it is in the holster.
And of course, KYFFOTFT.
Oh, and I've heard of several cops, even chiefs, shooting themselves with their guns. The more you handle the gun, especially fully loaded ones you are carrying, the more chance you will make a mistake.
This guy made that mistake. Learn from him.
A safe gun is a holstered gun!
