Several problems with the concept, bro.
1. Check your state laws. In many states, permit to carry gun covers ONLY guns; saps, blackjacks, weighted gloves etc. remain prohibited items for carry.
2. These are contact weapons, that keep you in punching distance and still require skill to use. Saps and jacks can be used to strike wrists and hands, but you're still in the other guy's kicking range, and you'll need very good timing.
3. Jacks, saps, and weighted gloves often end up being used for head strikes. High likelihood of fractured skulls, brain damage, eye damage...in short, "death or grave bodily harm." You are seen as armed man using a deadly weapon on unarmed man. Also, if he ends up crippled or dead, you are seen as having destroyed a guy you yourself didn't think needed that degree of force, or you would have used your gun. Not the easiest position to defend.
The pepper spray is a good choice, and needs its own training of course. You're right that it doesn't always work immediately, but then, neither do bullets. Check Georgia law to see if you're allowed to carry a "Civilian TASER," which might be another useful intermediate force option for you.
Best of luck,
