I think you should carry your DA revolver and a speed loader or two. You should also carry an assortment of loaded mags. I suggest Sig, Glock, and Beretta for this since they are popular. That way you have a better chance of picking up a handgun from the carnage and reloading it.
You should also never venture any more than 50' from a properly grounded lightning rod.
Carry what makes you comfortable doing the things you do.
I'm comfortable with a SA .357 and a SA 44 mag
It helps to know that you don't have to hit a boogerman 3 or 4 times to make him want to stop being a boogerman.
Now if I could just get them all to wear targets and stand very still at 15 to 25 yards...............
I wonder if that's why they made me carry a 45 pistol and two loaded spare magazines? It's a mystery I tell you, its a mystery and it will never be solved by mortal man till we are long gone and only remembered by dust blowing in the hot winds.
