yeah this is a fail move
i'm not saying i'm out to "kill someone" but if you're breaking into my house the last thing i really wanna do is scare you off and then give you another chance to come back when i'm not home, instead i'll be standing at the top of the stairs to meet you with a hail of gunfire that you'll never see coming so i dont have to worry about you coming back to harm my family
NOW, if I was the homeowner and I KNEW the perp had a gun, then yes my chamber would already be loaded.
I just practice good gun safety by having all of my guns unloaded in the house. Even if they are in a safe.
And for less experienced shooters, they are more likely to hit something with a shotgun than a handgun that they may have fired only a handful of times.
