Of course in setting up a plan, one needs to consider lifestyle, family & location.
For me it is only myself & Lady D, we live out in the country, close neighbor is 350 yds away. We live back a about 900 foot driveway.
We keep a 12 ga pump gun loaded with #4 Buck, we also keep a CAR-15 with 30 round mag (55 fmj) Of course there a few hidden pistols here & there.
We also have a selection of cool tactical lights like Blackhawk & Surefire, & others.
but the one I have for home defense I found at a discount store on sale for $9
V-1 Million Power Series™ Cordless/Rechargeable Spotlight .
It may not be taci cool, but it does throw a lot of light, & the cost was very affordable, & yes I will be shooting one handed if need me, but with fried cornea's I really doubt they will resist a whole lot.
