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.
