Flare guns for self defense? The gun store guys take a look:
They don’t look “ideal”, but they definitely are better than nothing. I can’t imagine there is a criminal out that that would want to be shot with something that burns so hot. Plus, the business end of the gun looks intimidating because of the large bore diameter, so they would likely get the crap scared out of them even if they didn’t immediately know it just shot flares.
God I love that Hi-Point testing suit (featured in the later half of this video)
