My "there is something going on in my urban back yard" thing that I grab if it looks moderate is an Uberti SAA in .45LC... Because it goes where I point it.
I've run so many rounds down that, or similar, firearms...
Last time I had it outdoors was when a young Mexican fellow drove his truck OVER a dumpster... Well, most of the way... And my next door neighbor and I had NO IDEA what was going on...
If I think that worse stuff is going to hit the air handler, I cower inside... With a .357 Winchester carbine.
However... I've wandered out the front door with that when I have had neighbors having problems.
