At home, I can change a lot of things, quickly and that is another scenario.
What you are wanting is a small pocket/purse handgun. You don't buy these to put on the nightstand. There for a while I carried a Glock 19 and a Colt Anaconda 6" "Just in case!!!"
The night I wrecked my truck we had to tell the cops how to find all the guns before it got hauled off to the junkyard. They pulled out the G-19, the Colt and a Mac-11.
If you feel the need to have that much firepower, maybe you hadn't ought to be there in the first place!!!
Seriously, think about that.
I've "been there done that, seen it happen and got luckt to not have gone to jail or killed".
I am all for protecting yourself and loved ones, I have no problem with gun, owned more than I can recal and kept the ones that I liked.
But a gun isn't the "end all, beat" all solution. You really have to think if taking someones life is the only option and make the decision NOW!!!
As I said, I have had to make that call, I managed not to have to injure anyone, just the threat I was willing to ended it. It's not a decision I would care to make again.
Use your brain a bit, avoid some of these places, or move. The brain is the best weapon/tool you have!
I hope you like the gun.
