I never carry pepper spray when carrying a firearm. The last thing I want if the SHTF is for a prosecutor to attempt to make the argument I could have sprayed the aggressor. I do carry pepper spray and a knife for those places that a firearm is not allowed. If the pepper spray does not stop them, then they are at least slowed down enough to stop them with the cane or knife.
After carrying a full duty belt for over 30 years. I try not to carry more then I half to.
You wouldn't like my carry belt them then. I carry two guns, 18 rounds of spare ammo for the SA revolver. A spare cylinder for the cap and ball BUG, and a Opinel N10 knife. I used to carry a fixed blade, but I did cut some weight with the Opinel, it only weighs 2 ounces. But back in the old days that old Motorola weighed more than both of my guns do now. And I no longer have to carry handcuffs, or a baton. I believe my cane is lighter than that micarta baton, or whatever it was made of.
BTW I love that Opinel, don't understand why I did not buy one years ago.
